C- Reactive Protein (CRP)

Indication: Early detection of Dengue virus (within first 5 days of fever). Why it's needed: NS1 test enables early treatment and monitoring to prevent complications like Dengue hemorrhagic fever.

Indication: Detects acute (IgM) or past (IgG) Dengue infection. Why it's needed: Confirms dengue in patients with fever, body pain, or rash — essential for outbreak control

Indication: Determines ABO and Rh status for transfusion, pregnancy, or surgery. Why it's needed: Prevents mismatched blood transfusion and Rh incompatibility in pregnancy.

Indication: Separates and measures serum proteins to detect abnormal levels. Why it's needed: Essential in diagnosing multiple myeloma, chronic inflammation, or liver/kidney disease.

Indication: Diagnoses current (IgM) or past (IgG) Chikungunya virus infection. Why it's needed: Confirms cause of fever, rash, or joint pain in endemic areas or during outbreaks.

Indication: Detects typhoid fever caused by Salmonella typhi. Why it's needed: Still used in some settings as a screening test for enteric fever, though with limited sensitivity.

Indication: Basic screening of fluids for infection or systemic disease. Why it's needed: Provides an overview of fluid chemistry to guide further microbiological or cytological analysis

Indication: Monitors sirolimus drug concentration in transplant patients. Why it's needed: Ensures therapeutic levels of immunosuppressants to prevent organ rejection.

Indication: Tumor marker for medullary thyroid carcinoma. Why it's needed: Also useful in monitoring calcium regulation and C-cell hyperplasia.
