Alpha-Fetoprotein (AFP) Rapid Test: 15-Minute Accurate POC Screening Solution

1. What Is Alpha-Fetoprotein (AFP) Rapid Test

Alpha-Fetoprotein (AFP) Rapid Test is a 15-minute POC immunoassay to detect AFP concentration in human whole blood/serum. This lateral flow assay product eliminates the need for complex lab operations, delivering readable results for users with no professional testing background.

In practice, this test is designed to screen abnormal AFP levels that are linked to hepatocellular carcinoma risk, chronic hepatitis and liver cirrhosis, filling the gap of fast on-site testing for primary medical scenarios.

Q: Is AFP Rapid Test a formal diagnostic tool for liver cancer?

A: No, it only serves as an auxiliary screening method. All positive test results need further confirmation via laboratory chemiluminescence testing and imaging diagnosis.

Q: What sample types are acceptable for Immuno Biotech’s AFP Rapid Test?

A: The kit supports whole blood (finger prick sample), serum and plasma, no pre-processing is needed for fresh finger prick whole blood samples to reduce operation steps.

2. Core Working Principle of AFP Rapid Test Kits

The test uses colloidal gold labeled monoclonal anti-AFP antibodies to bind with AFP antigens in user samples, forming immune complexes that move along the nitrocellulose membrane to capture target signals on the test line.

Industry consensus confirms that high-purity antibody pairing is the core factor to avoid false positive results for AFP rapid tests. Recent 2026 clinical studies indicate that kits with 2 different high-specificity monoclonal antibodies can reduce non-specific binding rate below 1.2%.

Q: What is the cutoff value of Immuno Biotech’s AFP Rapid Test?

A: The cutoff value is 20 ng/mL, which is aligned with the global clinical reference standard for normal human serum AFP levels.

3. Step-by-Step Operating Guide for AFP Rapid Test

Actual testing shows that the full operation process can be completed in 18 minutes maximum even by users with no prior training, following the steps below strictly to get accurate results:

1. Take out the test cassette and preheat it to room temperature (15-30℃) before opening the sealed foil bag
2. Add 2 drops (approx 100μL) of prepared sample to the sample well of the test cassette with the matched dropper
3. Add 1 drop of sample buffer immediately after sample loading, and start timing
4. Read and record the test results at 15 minutes; do not interpret results after 20 minutes to avoid wrong judgment

4. 2026 Performance Data Comparison of Mainstream AFP Test Solutions

The data below is collected from 1200 clinical sample verification tests conducted by Immuno Biotech R&D team in the first half of 2026, comparing 3 mainstream AFP testing solutions on the market:

"AFP rapid tests have become the first choice for large-scale population liver abnormality screening programs due to its low cost and easy operation, with over 72% of community public health projects adopting relevant products in 2026." - IVD Industry Global Development Report 2026

5. Common Use Scenarios for Immuno Biotech AFP Rapid Test

From past 3 years of global case applications, Immuno Biotech’s AFP rapid test has been deployed in more than 27 countries, covering multiple scenarios that have high demand for fast testing:

Q: Can this AFP Rapid Test be used for home self-testing?

A: The CE marked OTC version of the product is allowed for home self-test use, users only need to follow the illustrated instruction to complete the operation, no extra help required.

Q: What supporting services can bulk purchasers get from en.immuno-bio.com?

A: Global free shipping order over 5000 units, custom private label packaging, free operation training video, and 24/7 after-sales technical support for all distributors.

6. Correct Result Interpretation Rules

Three common result types can appear on the AFP rapid test cassette: valid negative result (only red line on control area), valid positive result (2 red lines on both control and test area), invalid result (no red line on control area, no matter test line show or not).

In practice, faint red lines appearing on the test area within 13-17 minutes are judged as weak positive results, users are suggested to take a second test with a new kit after 72 hours, then go to hospital for formal lab testing to confirm the AFP level.

7. Known Limitations and Application Notices

We explicitly state that the product can not replace formal clinical diagnostic tools, abnormal AFP results can also be caused by pregnancy, acute hepatitis and other non-malignant conditions, the test can only be used as auxiliary screening reference.

The kit has a 24 month shelf life when stored at 2-30℃, do not use test cassettes that exceed the expiration date, or have broken sealed packaging to avoid wrong test results.
