Tridot is a rapid immunochromatographic blood test that screens for antibodies to HIV‑1 and HIV‑2 in whole blood, serum, or plasma. It provides qualitative results in about 15 to 30 minutes and is used for initial HIV screening. Because it detects antibodies, there is a window period after infection; reactive results require laboratory confirmation and clinical follow‑up.

Tridot is a rapid point‑of‑care three‑dot immunoassay used to screen for antibodies to HIV‑1 and HIV‑2 in whole blood, serum, or plasma. It yields results in about 15–20 minutes; one dot is a control and the others indicate reactivity for HIV‑1/2. A reactive Tridot requires confirmatory laboratory testing, as it is a screening—not a definitive—diagnostic test.

ELISA is generally better for accuracy: laboratory-based, more sensitive/quantitative, and used for confirmation. Tridot (rapid strip tests) are faster, less costly, point-of-care and useful for screening or in low-resource settings but may have slightly lower sensitivity/specificity and more false results. Choice depends on needs: use ELISA for confirmation and Tridot for quick screening.

In Delhi, Tridot (rapid HIV 1/2) testing is usually free at government ICTC centres. In private labs/clinics it typically costs between ₹300 and ₹800 depending on facility and inclusions (counselling, confirmatory tests). Prices vary—call the testing centre or lab for the exact fee and ask whether counselling and confirmatory follow-up are included.

To prepare for a TriDot test: no fasting or medication changes are required—eat and drink normally. Bring photo ID and a list of current medicines, wear short sleeves for a finger-prick or blood draw, and allow time for pre- and post-test counseling and consent. Be aware of the HIV antibody window period (recent exposures may be missed); if recent, plan repeat testing as advised by the clinic.

TriDot’s AI-driven training plans typically run about $20–$50 per month (cheaper with annual billing). Live or dedicated coach packages cost substantially more—often $100–$300+ per month—or multi-month coaching programs that can total several hundred to a few thousand dollars per year depending on coach experience and services. Prices vary by plan, billing cycle, and add-ons; check TriDot for current rates.
