The 30-Second Exam Hall Shortcut: ⚡ Pathology-Clinical Match

⏱️ Save ~25 seconds

Common cold = Rhinoviruses (III); Haemozoin = Malaria parasite Plasmodium (I); Widal test = Typhoid fever (II); Allergy = Dust mites (IV)! Match: A-III, B-I, C-II, D-IV!

1 A. Common cold: Viral infection of upper respiratory tract caused by Rhinoviruses (III).
2 B. Haemozoin: Toxic malarial pigment released by ruptured RBCs during Plasmodium infection causing chills and recurring fever (I).
3 C. Widal test: Standard serological agglutination test used for confirming Typhoid fever (II).
4 D. Allergy: Exaggerated immune response elicited by environmental allergens like Dust mites (IV).
5 Matching order: A-III, B-I, C-II, D-IV -> Option (1) / A.

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Match Upper Respiratory Infection and Malarial Toxin

Rhinoviruses represent one such group of viruses which cause one of the most infectious human ailments - the common cold (A -> III). The rupture of RBCs during malaria is associated with the release of a toxic substance, haemozoin, which is responsible for the chill and high recurring fever (B -> I).

Step 2

Match Diagnostic Test and Allergy

Typhoid fever caused by Salmonella typhi is confirmed by the classic Widal test (C -> II). Common examples of allergens that trigger IgE-mediated allergic responses include mites in dust, pollens, animal dander, etc. (D -> IV).

Step 3

Assemble Combination

A-III, B-I, C-II, D-IV matches Option (1).

NTA Trap Alert: Haemozoin vs Haemosiderin

Confusing physiological iron-storage haemosiderin with toxic malarial haemozoin.

🛡️ How to avoid the -1 mark: Haemozoin is exclusively formed by Plasmodium digesting hemoglobin inside infected erythrocytes.
