Sample Testing and Preservation Quiz

What is the primary purpose of matching samples to accompanying documentation in a laboratory setting?

• To ensure the samples are fresh

• To verify the integrity and traceability of the samples

• To determine the mass of the samples

• To check the colour of the samples

Why is it important to label samples with a unique identifier?

• To make the samples look professional

• To assist in tracking and tracing samples throughout the testing process

• To ensure the samples are of good quality

• To determine the priority status of the samples

What should be included on a sample label to ensure proper identification?

• The colour of the sample

• The sample ID, dates and times of sampling, and source identification

• The name of the person who collected the sample

• The temperature at which the sample was stored

What is the purpose of the 'chain of custody' in sample management?

• To ensure samples are stored in the correct location

• To document the chronological history of the sample from collection to disposal

• To determine the mass of the sample

• To check the colour of the sample

What should be done if a sample appears atypical or not as expected?

• Ignore the sample and proceed with testing

• Record observations and report them to a supervisor

• Discard the sample without documentation

• Mix the sample with another to improve quality

Why is it important to transport samples under the correct conditions?

• To ensure the samples are aesthetically pleasing

• To prevent deterioration or contamination of the samples

• To reduce the weight of the samples

• To make the samples easier to handle

What is a potential consequence of testing a contaminated sample?

• The test results will be more accurate

• The test results may not represent the bulk material

• The sample will become more valuable

• The sample will change colour

What is the significance of the sample ID in a laboratory setting?

• It determines the colour of the sample

• It links the sample to its original bulk material

• It indicates the temperature at which the sample was stored

• It shows the mass of the sample

What should be checked before accepting samples for testing?

• The aesthetic appearance of the sample

• Compliance with acceptance criteria, including packaging and transport conditions

• The name of the person who delivered the sample

• The colour of the sample

What is the role of the Laboratory Information Management System (LIMS) in sample management?

• To determine the colour of the samples

• To automatically generate sample IDs for traceability

• To weigh the samples

• To store the samples at the correct temperature
