Sample Practice Questions

Try these 10 sample questions from the CSMLS General MLT Certification Examination practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

  1. 1An MLT receives blood from an asymptomatic outpatient with no infection diagnosis. Under routine practices, how should the specimen's infection risk be classified?

    1. A.Treat it as potentially containing a human pathogen.Correct answer: A
    2. B.Treat it as infectious only after a positive culture.
    3. C.Treat it as infectious only after a positive antibody test.
    4. D.Treat it as infectious only after symptoms are recorded.

    Explanation: PHAC states that routine practices treat patient specimens "as though they contain a human pathogen." An absent diagnosis or symptoms does not establish that the specimen is free of pathogens; culture, antibody testing and symptoms are not prerequisites for routine precautions.

    Reference: PHAC Human Diagnostic Activities guideline — 4.1.2 Routine Practices, Universal Precautions, and Standard Precautions

  2. 2Before accepting a test request, an MLT checks whether an unexpected result could be communicated to the correct clinical contact. Whose contact information should the requisition identify?

    1. A.The clinician collecting the specimen
    2. B.The clinician requesting the testCorrect answer: B
    3. C.The laboratory's medical director
    4. D.The patient's assigned ward nurse

    Explanation: WHO requires "contact information for the health care provider requesting the test." The requestor is identified rather than assuming that the collector, ward nurse or laboratory medical director is the appropriate requesting contact.

    Reference: WHO Laboratory Quality Management System Handbook — 5-3 Collection and preservation, printed p.64

  3. 3An MLT is selecting an optical method to identify birefringent crystals in synovial fluid. Which microscopy method is used for this examination?

    1. A.Inverted phase-contrast microscopy
    2. B.Compensated polarized light microscopyCorrect answer: B
    3. C.Epifluorescence microscopy
    4. D.Dark-field illumination microscopy

    Explanation: Mayo Clinic Laboratories lists "Compensated Polarized Light Microscopy" for identification of crystals in body fluid. This optical method assesses birefringence; phase contrast, fluorescence and dark field are other genuine microscopy methods but do not provide that compensated polarization assessment.

    Reference: Mayo Clinic Laboratories: Crystal Identification, Body Fluid — Method Name

  4. 4An MLT reviews an A1C result higher than expected from the patient's glucose measurements. Which clinical circumstance is associated with a falsely high A1C rather than a lower A1C?

    1. A.Recovery from acute blood loss
    2. B.Significant iron-deficiency anemiaCorrect answer: B
    3. C.Ongoing hemolytic anemia
    4. D.Successful iron replacement therapy

    Explanation: NGSP states: "Iron deficiency anemia, a major public health problem in developing countries, is associated with higher HbA1c and higher fructosamine". It also states that reduced erythrocyte survival lowers HbA1c; acute blood-loss recovery and hemolytic anemia are examples. Iron replacement lowers the elevated measurement. Iron deficiency is therefore the circumstance consistent with the positive discordance.

    Reference: NGSP: Factors that Interfere with HbA1c Test Results — Factors that affect interpretation of HbA1c Results

  5. 5Analytical QC is satisfactory, but specimens are being lost before testing and reports sent to incorrect destinations. Which approach provides the overarching framework for addressing failures across all these stages?

    1. A.Analytical quality control
    2. B.Laboratory quality management systemCorrect answer: B
    3. C.External analytical proficiency testing
    4. D.Instrument calibration programme

    Explanation: WHO states: "Assuring accuracy and reliability throughout the path of workflow depends on good management of all of the quality essentials." A quality management system covers the complete workflow beyond analytical control, calibration or proficiency testing.

    Reference: WHO Laboratory Quality Management System Handbook — 1-3, p. 13

  6. 6Before adapting to a new quality workflow, an MLT team compares current practices with a quality-system checklist to identify what must change. Which planning technique is being applied?

    1. A.Gap analysisCorrect answer: A
    2. B.Root cause analysis
    3. C.Proficiency testing
    4. D.Cost-benefit analysis

    Explanation: WHO recommends "gap analysis" to compare current practices with required good laboratory practices. This identifies needed changes rather than investigating a particular occurrence, comparing proficiency results or balancing financial costs and benefits.

    Reference: WHO Laboratory Quality Management System Handbook — 18-4 Organizational functions: planning, p. 216

  7. 7An MLT prepares a structured telephone discussion: the current problem, relevant clinical context, the MLT's assessment, and a requested next step. Which communication framework matches this sequence?

    1. A.STEP
    2. B.DESC
    3. C.I-PASS
    4. D.SBARCorrect answer: D

    Explanation: AHRQ states: "SBAR, which stands for Situation, Background, Assessment, and Recommendation (or Request), is a structured communication framework". These four elements match the intended discussion. STEP, DESC and I-PASS are other healthcare team tools with different structures.

    Reference: AHRQ TeamSTEPPS: SBAR — What SBAR Is

  8. 8An MLT posts a rare clinical case on social media without the patient's name. Other details could be combined with public information to identify the person. Which confidentiality risk remains?

    1. A.Unauthorized data destruction
    2. B.Loss of information availability
    3. C.Indirect patient re-identificationCorrect answer: C
    4. D.Unauthorized alteration of the record

    Explanation: CSMLS warns: "Information from one person can be correlated with information from another to allow piecing together a situation that identifies a very private matter or individuals." Removing the name alone does not prevent indirect identification; availability loss, alteration and destruction describe other security problems.

    Reference: CSMLS Code of Ethics — Code of Ethics Guidance, social media confidentiality discussion

  9. 9While uncapping patient specimen tubes outside a biological safety cabinet, an MLT identifies a risk of droplets reaching the eyes. Which PPE is specifically intended to protect that exposure site?

    1. A.A fluid-resistant gown
    2. B.Protective safety gogglesCorrect answer: B
    3. C.A disposable respirator
    4. D.Disposable nitrile gloves

    Explanation: The WHO handbook states, "Protection of eyes with goggles is strongly recommended as a routine procedure to prevent contact with these droplets." Goggles protect the eyes during uncapping. The other items address clothing, inhalation or hand exposure rather than ocular droplet exposure.

    Reference: WHO Laboratory Quality Management System Handbook — 2-7 Personal protective equipment, printed p.31

  10. 10A community nurse asks an MLT for the laboratory's current collection, preservation and transport instructions for a newly ordered test. Which laboratory document is designed to supply this information to collection sites?

    1. A.The equipment service log
    2. B.The quality control chart
    3. C.The laboratory handbookCorrect answer: C
    4. D.The internal audit report

    Explanation: WHO says the laboratory handbook "should be made available at all sample collection areas, including those that are distant from the laboratory." It provides collection and transport requirements. Maintenance logs, QC charts and audit reports have different functions.

    Reference: WHO Laboratory Quality Management System Handbook — 5-2 The laboratory handbook, printed p.63
