PRC March 2026 MTLE results

The MTLE is a two-day PRC Board of Medical Technology written licensure examination. The official syllabus assigns 20% each to Clinical Chemistry, Microbiology and Parasitology, Hematology, and Blood Banking and Serology, plus 10% each to Clinical Microscopy and Histopathologic Techniques with Medical Technology Laws and Ethics. The March 2026 PRC program schedules six 2-hour subject tests. RA 5527 requires a 75% general average with no rating below 50% in any major subject.

Sample MTLE Practice Questions

Try these sample questions to test your MTLE exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A serum specimen is visibly hemolyzed. Which analyte is most likely to be falsely increased because of release from red blood cells?
A.Sodium
B.Potassium
C.Glucose
D.Urea nitrogen
Explanation: Potassium is high inside red blood cells, so hemolysis can release intracellular potassium into serum and cause a falsely increased result. Hemolyzed specimens can also affect enzymes such as LDH and AST, but potassium is the classic electrolyte concern.
2Which additive is most appropriate when a blood glucose specimen cannot be separated from cells promptly and glycolysis must be inhibited?
A.Sodium fluoride with potassium oxalate
B.EDTA only
C.Heparin only
D.Sodium citrate only
Explanation: Sodium fluoride inhibits glycolysis, helping preserve glucose concentration when processing is delayed. Potassium oxalate is commonly paired with fluoride as an anticoagulant in gray-top tubes.
3A chemistry control result exceeds the laboratory's defined rejection rule. What should the technologist do before reporting patient results from that run?
A.Report patient results if they look clinically reasonable
B.Ignore the control because it is not a patient sample
C.Troubleshoot the run and withhold affected patient results until control is acceptable
D.Average the control result with yesterday's result
Explanation: Quality control monitors whether an analytical run is performing acceptably. If a rejection rule is violated, affected patient results should not be released until the problem is investigated and corrected.
4Which enzyme is more liver-specific and is commonly interpreted with AST when evaluating hepatocellular injury?
A.Creatine kinase
B.Alanine aminotransferase
C.Amylase
D.Alkaline phosphatase
Explanation: Alanine aminotransferase is relatively more specific for liver injury than AST, which is also present in cardiac and skeletal muscle. ALT and AST patterns help assess hepatocellular damage.
5Hemoglobin A1c is most useful because it reflects which clinical information?
A.Minute-to-minute blood glucose
B.Average glycemia over roughly the previous 2 to 3 months
C.Renal filtration rate on the day of collection
D.Pancreatic amylase secretion
Explanation: HbA1c forms by nonenzymatic glycation of hemoglobin over the red cell life span. It is used as an index of longer-term glycemic exposure, not a same-moment glucose value.
6Which handling step is most important for an arterial blood gas specimen?
A.Expose the syringe to room air before analysis
B.Analyze promptly and avoid air bubbles
C.Store uncovered at room temperature for several hours
D.Use a tube with clot activator
Explanation: Blood gas specimens must be collected anaerobically and analyzed promptly because gas exchange with air and ongoing metabolism change pH, pCO2, and pO2. Air bubbles should be expelled quickly and safely.
7A creatinine result by the Jaffe reaction is unexpectedly high in a patient with marked ketonemia. What is the most likely analytical issue?
A.Ketones may positively interfere with the alkaline picrate reaction
B.Ketones destroy creatinine before measurement
C.The Jaffe reaction measures only cystatin C
D.Ketonemia prevents all color formation
Explanation: The Jaffe creatinine method is susceptible to noncreatinine chromogen interference, including ketones in some settings. Enzymatic creatinine methods are often less affected by this specific problem.
8Which formula correctly calculates the serum anion gap using sodium, chloride, and bicarbonate?
A.Sodium minus chloride minus bicarbonate
B.Chloride plus bicarbonate minus sodium
C.Sodium plus chloride minus bicarbonate
D.Bicarbonate divided by chloride
Explanation: The common anion gap calculation is Na minus the sum of Cl and HCO3. It estimates unmeasured anions and is useful in evaluating metabolic acidosis patterns.
9In Westgard multirule quality control, what does a 1-3s rule violation usually indicate?
A.One control result exceeds plus or minus 3 standard deviations from the mean
B.Two consecutive controls are on the same side of the mean within 1 standard deviation
C.Ten controls are randomly scattered around the mean
D.A patient result is exactly at the reference interval midpoint
Explanation: The 1-3s rule is a rejection rule when a single control result exceeds the mean by more than 3 standard deviations. It strongly suggests random error or a significant analytical problem requiring investigation.
10A patient with severe hyperlipidemia has a low sodium result by an indirect ion-selective electrode method, but direct ISE sodium is normal. What best explains this discrepancy?
A.Pseudohyponatremia from reduced plasma water fraction
B.True sodium depletion from lipid loss
C.Chloride interference with all sodium electrodes
D.Excess sodium trapped inside red cells
Explanation: Indirect ISE methods dilute the specimen and assume a normal plasma water fraction. Marked lipemia or hyperproteinemia can reduce plasma water and cause pseudohyponatremia, while direct ISE is less affected.

MTLE Study Tips from Top Performers

1Study by the official 20/20/20/20/10/10 subject weights, but keep quality control, biosafety, specimen handling, and result integrity active in every subject.
2For Clinical Chemistry, practice preanalytical errors, calibration, QC rules, blood gas interpretation, toxicology screens, electrolytes, enzymes, and method interferences.
3For Microbiology and Parasitology, connect each organism to specimen source, stain, culture conditions, identification tests, susceptibility principles, and parasite morphology.
4For Hematology and Blood Banking, drill smear recognition, CBC corrections, coagulation patterns, antibody panels, compatibility testing, transfusion reactions, and component therapy.
5For Clinical Microscopy and Histopathology, practice urine sediment, CSF and serous fluid interpretation, semen analysis, tissue processing order, microtomy artifacts, cytology fixation, accessioning, RA 5527, and confidentiality.
6Use two-hour timed subject blocks because the PRC program schedules each MTLE subject as a 2-hour test.
