Validity
I’m slightly anxious about the validity of the results. If the blood that I use is contaminated in any way for example from excess tissue fluid, would the test produce a false negative result as the blood would be diluted?
Would you recommend wiping the first drop away and using the second to avoid this problem?

Hi Anonymous,
We would not recommend to use a home test that requires the end user to mix the diluent sample theirselves. Would you be able to tell the name of the test/manufacturer that you acquired the test from? I may be able to give a little more advice on the testing procedure.
Usually if users don't follow the instructions, the result is unreliable and can give a false reading. I would recommend to retest using a self-test or getting a test done at a clinic.
I hope this information helps.
Kindest regards,
Becky

Hi, i had a home test but i got just a little blood and mixed it up with more drops of the sample diluent. Immediately it flowed quickly within a minute and showed a positive results. I then read the instructions and found out the results much be shown in 15-20minutes and the diluent sample much be two drops. Actually i didn't follow the instructions since i was so in a hurry to see my status. Is this valid ?

Hi N,
No not at all, it really doesn't matter which finger you use, or if you used the second drop of blood. Squeezing the puncture site will have no affect and is sometimes recommended if users are unable to bleed.

Hi thanks for the reply.
Just for my own peace of mind if i use the second drop of blood will this affect the result?
And would squeezing the puncture site to get the drop of blood out affect the result?
Thanks.

Hi N,
The first drop of blood is totally fine and is recommended to be used. The BioSure self test has been through numerous studies to assess the validity, there is no evidence to suggest that the first drop of blood is diluted in any way that could affect the test or result itself.
I hope this helps.
Kindest regards,
Becky
