# Microsidd HIV Test Kit Comparison (2026) **By Microsidd India** · 2026-07-31 # Microsidd HIV Test Kit Comparison (2026) ## Compare HIV Antibody, 3rd Generation & 4th Generation HIV Test Kits Choosing the correct HIV test depends primarily on **how many days have passed since a possible exposure**. Different generations of HIV tests detect different markers of infection, which affects how early they can identify HIV. This comparison explains the differences between the three HIV rapid test kits available on **Microsidd.com**, including **window period, sample type, detection technology, price, intended users, and when each test is most appropriate**. > **Important:** No rapid HIV test can reliably detect infection immediately after exposure. If testing is performed during the window period, repeat testing may be recommended according to current medical guidelines. Positive rapid test results should always be confirmed using the recommended laboratory testing algorithm. * * * # Buy Online from Microsidd Product Price Buy Now **Microsidd HIV Antibody 1/2 Rapid Test Kit** **₹299** [https://microsidd.com/products/hiv-antibody-rapid-test-kit](https://microsidd.com/products/hiv-antibody-rapid-test-kit) **Microsidd HIV Test Kit – 3rd Generation** **₹399** [https://microsidd.com/products/hiv-test-kit-rapid-1-test](https://microsidd.com/products/hiv-test-kit-rapid-1-test) **Microsidd HIV Test Kit – 4th Generation (HIV Ag/Ab)** **₹699** [https://microsidd.com/products/4th-generation-hiv-test-kit](https://microsidd.com/products/4th-generation-hiv-test-kit) _Prices are based on the current Microsidd listings with free discrete delivery._ * * * # Quick Comparison Table Feature **Microsidd HIV Antibody 1/2** **Microsidd HIV 3rd Generation** **Microsidd HIV 4th Generation** Generation Antibody Rapid Test 3rd Generation 4th Generation Detects HIV-1 & HIV-2 Antibodies HIV-1 & HIV-2 IgM + IgG Antibodies HIV-1 p24 Antigen + HIV-1 & HIV-2 IgM/IgG Antibodies Earliest Detection Later infection Earlier than antibody-only tests Earliest among rapid tests Typical Window Period 23–90 days Approximately 20–90 days Approximately 18–45 days (antigen/antibody detection) Best Time to Test More than 3 months after exposure 3–12 weeks after exposure 2–6 weeks after exposure Sample Type Whole Blood / Serum / Plasma Whole Blood / Serum / Plasma Whole Blood / Serum / Plasma Sample Volume Small Finger-Prick Sample Small Finger-Prick Sample 5 µL (Approx. 2 Drops) Test Time 15 Minutes 15 Minutes 15 Minutes Detects Early Infection No Better than antibody-only Yes (p24 Antigen + Antibodies) Suitable for Home Use\* Under professional guidance Under professional guidance Under professional guidance Price **₹299** **₹399** **₹699** * * * # Understanding HIV Test Generations ## 1️⃣ Microsidd HIV Antibody 1/2 Rapid Test ### Best for - Routine HIV screening - Testing more than **90 days after possible exposure** - General health check-ups - Individuals without recent high-risk exposure ### Detects - HIV-1 antibodies - HIV-2 antibodies ### Advantages - Economical - Simple rapid procedure - Reliable after the antibody window period - Suitable for hospitals, clinics and screening programmes * * * ## 2️⃣ Microsidd HIV 3rd Generation Rapid Test ### Best for - Moderate-risk recent exposure - Earlier antibody detection than first-generation antibody-only methods - Individuals testing **approximately 3–12 weeks after exposure** ### Detects - HIV IgM antibodies - HIV IgG antibodies - HIV-1 & HIV-2 antibodies ### Advantages - Earlier detection than standard antibody-only tests - Good balance between cost and early detection - Frequently used in diagnostic laboratories and healthcare settings * * * ## 3️⃣ Microsidd HIV 4th Generation Rapid Test ### Best for - Recent high-risk exposure - Need for earlier detection - Healthcare professionals - Higher-risk clinical screening ### Detects - HIV p24 Antigen - HIV-1 IgM - HIV-1 IgG - HIV-2 antibodies ### Advantages - Earliest detection among rapid HIV tests - Detects infection before antibodies alone become detectable - Reduces the diagnostic window compared with antibody-only testing - NIB evaluated and designed for professional use according to the Microsidd product information. * * * # Which HIV Test Should You Choose?

The **Microsidd 4th Generation HIV Test Kit** detects both **p24 antigen and HIV antibodies**, allowing earlier detection than antibody-only rapid tests. ### Which HIV test is best after a recent exposure? For people testing within the first few weeks after a possible exposure, the **4th Generation HIV Test Kit** is the preferred rapid test because it detects both antigen and antibodies. ### Which HIV test is best for routine screening? If the possible exposure occurred more than three months ago or for routine screening, the **Microsidd HIV Antibody 1/2 Rapid Test** provides a cost-effective option. ### What sample is required? All three Microsidd rapid HIV test kits are designed for use with **whole blood, serum, or plasma**, following the instructions supplied with each kit. The 4th Generation kit requires approximately **5 µL** of specimen. ### Can a negative test rule out HIV? A negative result is meaningful only when the test is used outside its applicable window period. If testing occurs soon after a possible exposure, repeat testing may be recommended according to clinical guidance. Positive rapid test results require confirmatory laboratory testing. * * * # Final Recommendation If Your Priority Is...
