Which enzyme is most specific for myocardial infarction when elevated?
Answer: Troponin I
Cardiac troponin I is highly specific to cardiac muscle and is the gold standard biomarker for myocardial infarction.
A fasting glucose of 135 mg/dL on two separate occasions is diagnostic of:
Answer: Diabetes mellitus
A fasting plasma glucose ≥126 mg/dL confirmed on two occasions meets ADA criteria for diabetes mellitus diagnosis.
Which lipoprotein is considered 'good cholesterol' due to its role in reverse cholesterol transport?
Answer: HDL
HDL transports cholesterol from peripheral tissues back to the liver for excretion, reducing cardiovascular risk.
The normal anion gap range is approximately:
Answer: 8–12 mEq/L
The normal anion gap (Na − [Cl + HCO3]) is 8–12 mEq/L, representing unmeasured anions like albumin and phosphate.
Hemoglobin A1c reflects average blood glucose over approximately what time period?
Answer: 2–3 months
HbA1c reflects glycation of hemoglobin over the 2–3 month lifespan of red blood cells.
Elevated serum amylase and lipase are most indicative of:
Answer: Acute pancreatitis
Both amylase and lipase are released from damaged pancreatic acinar cells during acute pancreatitis.
