Question

Match List I (Biochemical Abnormality) with List II (Clinical Diagnosis) and select the correct answer using the codes given below the Lists:

List I (Biochemical Abnormality)	List II (Clinical Diagnosis)
A. Raised alkaline phosphatase	1. Pheochromocytoma
B. Raised serum amylase	2. Grave's disease
C. Raised urinary VMA levels	3. Obstructive jaundice
D. Raised serum T4	4. Acute pancreatitis

• A. A-3, B-4, C-1, D-2
• B. A-3, B-4, C-2, D-1
• C. A-4, B-3, C-2, D-1
• D. A-4, B-3, C-1, D-2

Hint:

Each marker here points to one well-known diagnosis; match them directly rather than guessing.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This match-list question pairs four biochemical abnormalities with the clinical diagnoses they point to, testing whether specific biochemical markers can be linked to the conditions that classically raise them.

Step 2: Key Concept or Approach:
Each biochemical marker in this list has one dominant clinical association taught in physiology and medicine: alkaline phosphatase rises with cholestasis, amylase rises with pancreatic inflammation, urinary VMA rises with catecholamine-secreting tumours, and total T4 rises with hyperthyroidism.

Step 3: Working Through the Options:
Raised alkaline phosphatase (A) is a marker of cholestasis, seen when bile flow is blocked, so it pairs with obstructive jaundice, option 3. Raised serum amylase (B) is released from an inflamed pancreas and is the standard biochemical marker used to support a diagnosis of acute pancreatitis, so it pairs with option 4. Raised urinary VMA, vanillylmandelic acid (C), is a breakdown product of catecholamines and is markedly elevated in phaeochromocytoma, a catecholamine-secreting adrenal medullary tumour, so it pairs with option 1. Raised serum T4 (D) reflects excess thyroid hormone production, the hallmark of hyperthyroidism, of which Grave's disease is the most common cause, so it pairs with option 2.

Step 4: Conclusion:
The correct match is A-3, B-4, C-1, D-2: raised alkaline phosphatase with obstructive jaundice, raised amylase with acute pancreatitis, raised urinary VMA with phaeochromocytoma, and raised T4 with Grave's disease.
