, MLT ASCP Practice Exam 2026: 40 Q&A with Explanations
1. A patient presents with severe fatigue and excessive urination. Their initial glucose result
exceeds the analytical measurement range. The technologist creates a dilution by adding 250 µL
of serum to 750 µL of diluent. The diluted sample reads 340 mg/dL. What is the correct reported
glucose value?
A. 340 mg/dL
B. 975 mg/dL
C. 1360 mg/dL
D. 1700 mg/dL
Answer: C
Explanation: The dilution is 1 part sample to 3 parts diluent, making a 1:4 dilution. The dilution
factor is 4. The corrected result is calculated by multiplying the diluted result by the dilution
factor: 340 mg/dL x 4 = 1360 mg/dL.
2. In a Christensen's urea agar test, only the slant portion of the tube turns pink, while the butt
remains yellow. What does this pattern indicate about the organism's urease activity?
A. Strong urease activity
B. Weak urease activity
C. Inoculation error
D. Use of expired media
Answer: B
Explanation: A pink slant and yellow butt indicate weak urease activity. The enzyme is only
active enough to hydrolyze the small amount of urea that has diffused into the slant. Strong
urease producers would cause both the slant and the butt to turn pink rapidly.
3. What is the initial step in the Polymerase Chain Reaction (PCR) process?
A. Annealing
B. Extension
C. Denaturation
D. Hybridization
Answer: C
Explanation: The first step of PCR is denaturation, where the double-stranded DNA template is
heated to separate it into two single strands.
