4. Which of the following conditions may cause elevated levels of alkaline phosphatase
(ALP)?
A) Liver disease
B) Bone disorders
C) Biliary obstruction
D) All of the above
Answer: D) All of the above
Rationale: Elevated ALP can indicate liver dysfunction, bone disease, or bile duct obstruction.
5. What is the main purpose of molecular diagnostics in clinical laboratories?
