Patient Preparation Instructions

Patient preparation instructions are essential for accurate test values.

Fasting is the most common patient preparation instruction.

Patients should not eat or drink anything but water for a certain period of
time before a blood draw.

Most fasting blood tests require a 12 hour fast.

Certain substances in the blood can be affected by fluid intake and food.

For example, patients should fast prior to having a lipid panel.Meal intake
prior to the test can lead to elevated lipid levels.

Medication restrictions may also be a patient preparation requirement.

Verify that all preparation guidelines were followed prior to phlebotomy
procedures.

Approaching Patients with
Care

Introduce yourself and approach
each patient with a pleasant, warm
demeanor.

Some patients have little or no issue
with blood collection, while others
may have anxiety.

Make patients as comfortable as
possible and be sensitive to their
needs.

Ensure effective communication and
accurate skills when dealing with
children.

5

media

Preparing for Venipuncture

Seat the patient in a comfortable, well lit area.

Position the patient with their arm extended out.

Use a phlebotomy chair with an extended armrest if available.

If not, have the patient make a fist with the opposite hand and place it
behind the elbow of the arm being used.

This ensures the arm stays straight and stable during the procedure.

For pediatric patients, a support person can assist in holding the patient's
arm still.

Communication and accurate skills are necessary when dealing with
children.

Question patients about previous blood draws and any reactions they have
had.

Prepare for possible adverse reactions and make necessary adjustments
or accommodations.

DETERMINE ORDER OF DRAW

Vacuum stopper tubes are identified by the color of the top of
the tube, which also identifies any additive within the tube. The
tubes must be drawn in the proper order to avoid
cross-contamination of the additives. If the tubes are not drawn
in the correct order, the additives could inadvertently affect
laboratory results.

The order of blood tube draw is critically important to avoid
errors. During the blood draw process, the additive from
one tube can carry over to another and affect test results.

DETERMINE VENIPUNCTURE SITE ACCESSIBILITY

The preferred vein within the antecubital space is the median cubital vein, as this
area tends to cause less pain and this vein is the least likely to roll during the
procedure. If the median cubital vein is not easily palpated or is covered with scar
tissue, the cephalic vein and basilic veins—found on either side of the median
cubital vein—are often strong alternatives.

If these veins within the antecubital space are inaccessible, the back of the hand,
wrist, and foot are also options. Blood draws from the foot should only be
performed under the supervision of a provider due to the risk of deep vein
thrombosis (DVT). When drawing from the hand, be aware that these veins are the
most likely to roll. Additionally, the back of the hand contains many nerves, which
can lead to more discomfort for the patient. Reasons for looking at these alternative
sites include circumstances in which both antecubital spaces have scars, bruises, or
burns or are swollen

Procedure

To begin site selection, have the patient extend an arm out and straighten the
elbow. Always inspect both arms. Palpate the antecubital area by pushing up and
down on the patient’s skin. Veins have a bouncy feel. The size, depth, and direction
of the vein should be determined. Veins that are highly visible but do not have
bounce to them should be avoided, as a successful draw is unlikely.

Tourniquet Application

A tourniquet should be applied to the patient’s arm about 3 to 4 inches above the
draw site to make the vein easier to palpate and more readily accessible for the
blood draw. A tourniquet should not be left in place for longer than 1 minute.
Leaving the tourniquet on longer than 1 min can cause hemoconcentration and
alter test results.

Site Restrictions

During site selection, check with the patient regarding possible restrictions due to
fistulas, ports, or mastectomy. Avoid drawing blood from the same side of the
body in which any of these conditions are present.Additionally, avoid selecting site
locations with scar tissue, injuries, burns, or wounds.

67

Multiple Choice

23. Where should the tourniquet be placed on the patient during the venipuncture procedure?

1

A. 1 inch above the vein puncture site

2

B. Over the vein puncture site

3

C.3-4 inches above the vein puncture site

4

D. 3 inches below the vein puncture site

68

media
media

PREPARE SITE FOR VENIPUNCTURE

Cleanse the site with antiseptic, wiping in an upward-and-downward motion with friction. Allow the site to
air-dry, and the tourniquet will be reapplied after the site is dry. Avoid touching the site again after cleansing,
even with gloves on. Avoid blowing on the area or waving hands over it to dry the alcohol faster, as this can
contaminate the skin.

PERFORM VENIPUNCTURE

To begin the procedure, anchor the vein by grasping the skin firmly about 2 to 3 inches below the
puncture location, holding the skin taut. This ensures the vein is stabilized.

When drawing from the arm, insert the needle smoothly and quickly at about a 15- to 30-degree angle
depending on the depth and position of the vein.

When drawing from the patient’s hand, the correct angle of insertion is lower, about 10 to 15 degrees, as
the veins in the hand are smaller and thinner.

The bevel of the needle should be facing upward.

Once the needle is in place, with the nondominant hand, insert the evacuated stopper tube into the
needle holder until blood flow is established. Watch the needle and avoid any additional movement of the
needle.

Once proper blood flow is established, release the tourniquet with the nondominant hand.

69

media
media

When the tube has exhausted the vacuum and the tube is full, remove the tube, gently
inverting as necessary. If more than one tube is required, fill up the remaining tubes
using the correct order of draw.

Once all needed tubes are full and inverted as needed, apply the gauze over the needle
with the nondominant hand, not applying pressure until the needle is out of the patient’s
arm.

With the dominant hand, close the needle safety guard and dispose of the needle in the
biohazard sharps container.

PERFORM CAPILLARY PUNCTURE

Capillary punctures are performed when only a small amount of blood is needed for testing or
when immediate results can be acquired. It is the preferred method of blood collection for
infants and young children, but it can also be utilized with adults. Capillary blood is a mixture of
blood from arterioles, venules, capillaries, and intracellular and interstitial fluids. Due to this
mixed composition, not all testing should be performed using capillary blood.

70

media
media
media

Location of Capillary Punctures for Adults and
Infants

The preferred puncture site for obtaining a capillary puncture in adults and
children is the middle or ring finger of the nondominant hand. This procedure is
also commonly referred to as a fingerstick. Perform the puncture slightly off-center,
avoiding the central fleshy part of the fingertip, fingernail, and nail bed.

Infant capillary puncture will be performed on the outer edge of the underside of
the heel.
Note:
Never perform capillary puncture on the finger of an infant, as risk of damage to
the bone is high.

Take Note
Never perform capillary puncture
on the finger of an infant, as risk

72

media
media

Warm the patient’s hands prior to the procedure by having the patient rub them together or run
them under warm water. For infants, heel warmers can be used on the infant’s heel prior to
performing the puncture.

Cleanse the area with a 70% isopropyl alcohol pad and allow the site to air-dry completely. Avoid
touching the site after cleaning.

Performing the Puncture

Hold the patient’s finger between your thumb and forefinger firmly but gently. Hold the lancet device in your
dominant hand and at a right angle to the desired puncture site on the patient’s finger or heel. Activate the
spring or trigger system on the lancet and discard the used lancet into a sharps container immediately.

Wipe away the first drop of blood unless performing a prothrombin time (PT) test. This is to obtain a clean
sample without any tissue or fluid contaminants. Collect the required amount of blood. If the blood is slow to
flow, a gentle pressure and rubbing can be applied to the patient’s finger.

Once the specimen has been collected, place a clean gauze pad over the puncture site and ask the patient to
apply pressure to the area. Properly handle the collection container. Once the specimen and container are
intact, remove the gauze from the patient’s finger to assess hemostasis. If blood flow has slowed or stopped, a
bandage can be applied. If blood flow is still considerable, apply additional gauze and pressure. For excessive
blood flow from the puncture site, elevate the arm over the level of the heart to aid in hemostasis.

73

media
media

Order of Draw for Microcapillary Tubes

The recommended order of draw for capillary blood collection is different from blood
specimens drawn by venipuncture. The Clinical and Laboratory Standards Institute
recommends the following order of draw for skin puncture.

Blood gases

EDTA tubes

Other additive tubes

Serum tubes

Following phlebotomy or capillary puncture, apply a gauze pad over the puncture site
with pressure until the bleeding stops. The arm should be extended and elevated
above the level of the heart if needed. Once bleeding has stopped, apply a clean gauze
pad and bandage to the area.

Instruct patients to leave the bandaging in place for a minimum of 15 min.

74

media
media
media

Match and Label Specimen to Patient and Completed
Requisition

Labeling of specimen containers is another key step in proper specimen handling. Laboratory errors can occur
due to mislabeling of specimens. Blood collection tubes should be labeled immediately after the procedure is
completed—before the tubes are moved away from the area where the procedure takes place.

If the office does not have printed labels for specimens, the specimen label will need to be handwritten using
permanent marker, labeling the patient’s full name, date of birth, date and time of collection, and the MA’s
initials. Many lab requisitions come with adhesive numbered labels that can be affixed to all specimen
containers associated with the requisition. This is another verification step to help avoid errors.

Match each specimen tube with the laboratory requisition form when placing it in a biohazard transport bag.

Processing and Labeling Requirements

Some specimen tubes require processing prior to being transported to the laboratory. Ensure all
specimen tubes are labeled prior to processing. Check blood processing requirements in the laboratory
directory if needed.

Serum must be allowed to stand upright at room temperature for 30 to 45 min before being

centrifuged. However, blood specimens should not be allowed to stand for longer than 1 hour.

This will cause leaching of substance changes and changes to the integrity of the serum.

Clotted blood must stand upright at room temperature for 30 to 45 min.

HANDLE BLOOD SAMPLES AS REQUIRED FOR DIAGNOSTIC PURPOSES

Each specimen has specific handling instructions, including whether the tube should be centrifuged, proper
storage temperature (room air, refrigerated, or frozen), and guidelines regarding exposure to light. The
reference laboratory where the specimen will be sent for testing can be called for assistance with specimen
handling guidelines.

There are some blood tests that require specific timing, specific patient preparation, or handling of the
blood specimens.

PROCESS BLOOD SPECIMENS FOR LABORATORY

Centrifuge and Aliquot

During centrifugation of blood specimens, the blood collection tubes rotate at a high rate of speed. The amount of
time a specimen needs to be centrifuged varies. Allow serum specimens to clot prior to centrifugation.

The weight in the centrifuge must always be balanced. If the MA has multiple tubes of blood to be spun, place
tubes of the same size and containing similar amounts of blood across from one another. This ensures balanced
weight distribution while the centrifuge is in motion.

Aliquot Samples

Aliquot occurs when a single specimen
must be divided into multiple tubes for
testing on different equipment.

Use a single-use pipette for transfer of
the serum from one tube to another.

Always use a disposable pipette to
avoid splashing and spills. Label the
tubes appropriately.

81

media
media

PREPARE SAMPLES FOR TRANSPORTATION TO A REFERENCE (OUTSIDE) LABORATORY

Arrange transportation of the samples as soon as possible after collection. Have all specimens
labeled, requisitions completed, and everything packaged together in anticipation of the
laboratory transport arrival. Confirm specimen pickup before leaving the clinic each day.

Storage Conditions Related to Sensitivity to Light and

Temperature

All specimens should be placed into a clearly marked biohazard bag. Specimens that are to be stored and
transported at room air temperature do not require any special management. Extra care should be taken
for these specimens if they will be left in a lockbox outside the clinic for pickup by the lab when the
outdoor temperature is extremely high or low. Specimens that are to be refrigerated should be kept in a
medical-grade refrigerator that is not used for anything other than specimens. They should be packaged
according to lab instructions for transport. Specimens needing to be stored frozen should be kept in a
medical-grade lab freezer used only for specimens until the time of transport. Note that a specimen
should never be moved to the cooler bag until it is already completely frozen.

Specimens for certain tests must be protected from light to avoid changes to the specimen that could
impact results. When processing these samples, keep the lights in the lab low or off. Once the specimen
has been processed, it should be wrapped in foil to block out light or moved to a special amber transport
tube designed for light protection. Always store specimens following their specific handling requirements
while awaiting retrieval by the laboratory transportation service.

appropriate laboratory requisition with the patient’s name and identification information and contained
within the same biohazard bag to process the specimens. Use a separate biohazard bag for each patient’s
specimens.

FOLLOW GUIDELINES IN DISTRIBUTING LABORATORY RESULTS

Laboratories can send patient laboratory report results via email, fax, or directly to the
electronic medical record. Providers are required to review and acknowledge all results
prior to their inclusion in the medical record. Ensure the provider reviews the lab
reports in a timely manner and patients are contacted accordingly. The role of the
medical assistant often includes notifying patients of their results as directed by the
provider, instructing or educating patients on any changes due to laboratory results,
and scheduling follow-up appointments for patients to review the results with the
provider.

RECOGNIZE AND RESPOND APPROPRIATELY TO OUT-OF-RANGE TEST RESULTS

When reporting abnormal or out-of-range laboratory results, some circumstances require immediate
notification of the ordering provider and documentation that the provider was notified.

The provider should review all laboratory reports and be notified of out-of-range results. Emergent results
can be referred to as critical lab results or critical lab values.

In general, critical results are those that indicate a life-threatening emergency for the patient if immediate
intervention does not occur.

It is within the scope of the medical assistant to receive this information and report it to the provider.
Understanding the impact on the patient should there be any delay in the process is crucial for effective
time management and prioritization of the patient.
