Specimen transport, handling and processing

Tubes should remain upright during transport to

• make sure the label is easy to read

• fit safely and securely into the tube rack

• prevent sample contamination due to prolonged contact with the stopper

• prevent the possibility of the sample leaking around the stopper

One of the primary causes of inaccurate lab results is

• insufficient sample volumes

• glycolysis

• improper specimen handling

• hemodilution

The maximum amount of time allowed between collection and separation of cells from plasma or serum is

• 30 minutes

• 1 hour

• 2 hours

• 4 hours

A test for this component requires that the specimen be kept warm

• RBC

• Cryofibrinogen

• Bilirubin

• Lactic Acid

In order to centrifuge a specimen clotting must take place; this could take approximately how much time in a red, gold or tiger top tube?

• 1 - 2 minutes

• 2 hours

• 24 hours

• 30 - 60 minutes

The major risk or concern about stopper removal is

• blood leakage

• aerosol formation

• clot removal

• increase processing time

The most common light sensitive test is

• lactic acid

• ABG

• Cryofibrinogen

• Bilirubin

A stat requisition should be delivered to the lab

• Within an hour of being drawn

• 30 - 45 minutes after being drawn

• within 30 minutes of being drawn

• immediately after being drawn

PPE recommended by OSHA standards for lab staff use during collection and processing include all of the following except

• Gloves

• Lab coat or cover gown

• respirator or NIOSH approved mask

• Goggles or protective face gear

Transport of bilirubin should be

• on ice

• in an amber colored tube

• in a pre-warmed tube with a heel warmer

• no special transport measures are needed
