The Bioline rapid HIV test kit manufactured by South Korea has been found to be faulty.

The WHO has recommended all countries to put on hold the use of Bioline test kits.

If your Doctor is still using the Bioline test kit, please alert him to this.

If you have been tested using the Bioline test kit, please see your doctor and speak to him/her about the need for a retest.

Update 2013 – SD Bioline has worked with WHO and implemented the necessary corrections. WHO has lifted it’s warning on SD Bioline test kits and it is now being used in various healthcare settings.

  3. Hi Dr Tan

    What are chances of false negative.Do rapid test have the same accuracy pf EIA test.Thx

    • Depends on what type and brand of rapid test. Some rapid tests like the Determine, has sensitivities and specificities exactly the same as lab based EIA. As a very general statement, lab based EIAs are more sensitive than rapid tests. The most common cause of false negatives is testing within the window period.

  4. Hi Dr. Tan,

    I was tested negative sometime back in 2013, but I can’t remember the exact date, using the 20minutes rapid test.

    Is there a need for re-test because I had just read the article of faulty test-kits

    • As long as it is after 3 months from your exposure, you do not need to retest.

  5. so dr tan as for your study what brand of test kit is the best to use?

    • drtan

      There is no ‘best’ test kit. It all depends on the doctor who is doing the test for you. For myself personally, I have had most experience with the Determine HIV 1/2 by Alere and the OraQuick. So I can advise patients thoroughly on their performance characteristics. Please post any follow up questions on http://www.askdrtan.com
