Introduction
This comprehensive assessment is designed to evaluate the knowledge, technical
proficiency, and critical thinking required of a Medical Laboratory Technician. It
rigorously tests general laboratory operations, clinical chemistry, hematology,
coagulation, immunology, immunohematology, blood banking, microbiology, and
urinalysis. The exam employs multiple-choice and scenario-based questions
emphasizing real-world application, quality control, safety, and adherence to AMT
certification standards. Mastery of these domains is essential for competent
laboratory practice and certification success.
SECTION ONE: QUESTIONS 1–200
,GENERAL LABORATORY
1. A laboratory technician is preparing a 1:10 dilution of a patient's serum for a
chemistry assay. If the total volume needed is 2 mL, how much serum and
diluent should be used?
A. 0.1 mL serum + 1.9 mL diluent
B. 0.2 mL serum + 1.8 mL diluent
C. 0.5 mL serum + 1.5 mL diluent
D. 1.0 mL serum + 1.0 mL diluent
RATIONALE: A 1:10 dilution means 1 part serum to 9 parts diluent. For a total
volume of 2 mL, divide 2 mL by 10 parts = 0.2 mL per part. Therefore, 0.2 mL
serum + 1.8 mL diluent.
2. According to the Clinical Laboratory Improvement Amendments (CLIA), which
of the following tests is classified as waived?
A. Complete blood count
B. Prothrombin time
C. Urine dipstick for glucose
D. Blood glucose meter testing
RATIONALE: CLIA-waived tests are simple, have a low risk of error, and include
urine dipsticks, blood glucose meters, and certain rapid strep tests. CBC, PT, and
most chemistry panels are moderate or high complexity.
3. A technician is performing a manual WBC count using a hemocytometer. The
dilution is 1:20. The technician counts 80 cells in the four large corner squares.
What is the WBC count per microliter?
A. 4,000/µL
B. 8,000/µL
C. 10,000/µL
D. 16,000/µL
RATIONALE: WBC count/µL = (cells counted × dilution) / (volume counted).
Volume of 4 corner squares = 0.4 mm³. WBC = (80 × 20) / 0.4 = .4 =
,4,000/µL. Wait: (80 × 20) / 0.4 = 4,000. But the correct formula is (cells × dilution
× 10) / number of squares. For 4 squares: (80 × 20 × 10) / 4 = 4,000. The correct
answer is 4,000/µL. Let me recalculate: WBC/µL = (number of cells counted ×
dilution factor × 10) / number of squares counted. (80 × 20 × 10) / 4 = 16, =
4,000. So the answer is 4,000/µL, which is option A.
4. Which of the following is the most appropriate method for disposing of used
sharps in the laboratory?
A. Recap the needle and place it in a regular trash bin
B. Place the sharp in a red biohazard bag
C. Place the sharp directly into a puncture-resistant, leak-proof sharps
container
D. Disinfect the sharp with bleach and dispose of it in regular trash
RATIONALE: Used sharps must be placed directly into a puncture-resistant,
leak-proof, closable sharps container that is labeled with a biohazard symbol.
Recapping is prohibited, and sharps should never be placed in regular trash or
biohazard bags.
5. A chemistry analyzer is calibrated. Which of the following best describes the
purpose of calibration?
A. To verify the accuracy of the analyzer over time
B. To establish the relationship between the instrument's signal and the
concentration of the analyte
C. To ensure the instrument is functioning within temperature specifications
D. To determine the precision of the instrument
RATIONALE: Calibration establishes the mathematical relationship between
the instrument's measured signal (e.g., absorbance) and the known concentration
of the analyte, allowing accurate quantification of unknown samples. Accuracy
verification is done with controls.
6. A laboratory technician is reviewing a Levey-Jennings chart. The 1₂s rule is
violated. What is the appropriate action?
, A. Reject the run and repeat all patient samples
B. Continue the run but monitor closely; this is a warning rule
C. Immediately shut down the analyzer
D. Report results with a disclaimer
RATIONALE: The 1₂s rule is a warning rule. It signals that one control value is
beyond ±2 standard deviations. The run may be reported if no other rejection
rules are violated, but the technologist should inspect the chart for trends or
shifts.
7. Which of the following is the primary purpose of a laboratory safety manual?
A. To document employee vacation schedules
B. To outline procedures for handling hazardous materials, emergencies, and
safe work practices
C. To list patient test results
D. To record instrument maintenance logs
RATIONALE: The safety manual is a comprehensive document that describes
safe work practices, hazard communication, emergency procedures, and handling
of biological, chemical, and radioactive materials.
8. A patient's specimen is labeled with a name that does not match the
requisition. What is the appropriate action?
A. Correct the label and proceed with testing
B. Reject the specimen and request a properly labeled new specimen
C. Notify the physician and proceed with testing
D. Test the specimen and note the discrepancy
RATIONALE: A mislabeled specimen is a critical pre-analytical error that can
lead to patient harm. The specimen must be rejected, and a new, correctly
labeled specimen must be collected.
9. Which of the following best describes the term "precision" in laboratory
testing?
