Which blood collection tube additive is used for coagulation studies such as PT and aPTT?
Answer: Sodium citrate (light blue top)
Sodium citrate (light blue top) chelates calcium to prevent clotting and is the required anticoagulant for coagulation factor studies.
When a urine specific gravity reading is 1.030, this indicates:
Answer: Highly concentrated urine with high solute load
A specific gravity of 1.030 is at the high end of the reference range, indicating highly concentrated urine with a significant solute load.
What is the purpose of using an internal standard in mass spectrometry-based laboratory testing?
Answer: To correct for matrix effects and variations in sample preparation
An internal standard, added to each sample, corrects for variability in extraction efficiency, matrix effects, and instrument response.
A laboratory receives a hemolyzed specimen for a potassium assay. The correct action is to:
Answer: Reject the specimen and request a new collection
Hemolysis falsely elevates potassium (RBCs contain high intracellular K+), so the specimen must be rejected and recollected to ensure accurate results.
Which organization is responsible for certifying medical technologists in the United States with the MT(ASCP) credential?
Answer: American Society for Clinical Pathology Board of Certification (ASCP BOC)
The ASCP Board of Certification administers the Medical Technologist (MT) certification examination and issues the MT(ASCP) credential.
The Beer-Lambert Law, used in spectrophotometry, relates absorbance to:
Answer: Concentration and path length of the analyte
Beer-Lambert Law states that absorbance equals the product of molar absorptivity, path length, and concentration (A = εlc).
Standard precautions in the clinical laboratory require that:
Answer: All human blood and body fluids are treated as potentially infectious
Standard precautions assume all blood and body fluids may be infectious regardless of the patient's known diagnosis, protecting staff universally.
