Faint control line

I had real trouble getting enough blood for the test and after about 15-20 mins the control line did show very, very faintly although there was a definite line. There were no other lines. Can I take that as a negative even though it was so faint?

Hi Peggy, Sorry I'm not quite sure what you mean when you say 'patient line'. Would you please be able to elaborate? Thank you. Becky

The patient line is very visible but the control line is very faint what does it mean?

Like Worrier 1234 I wasn't sure of the control line too because It's intensity was not assuring although it was clearly visible .

Hello i just used a HIV home testing kit and the results aren’t so much clear. There’s only one very faint line on the Control area and the Test area has no line at all. What does this mean? Please note that the C line is faint.

The safety lancet did not help me to get enough blood and it could only be used once which means I did not have enough blood for the test to work. So now I have spent £30 and still not got any answers about whether I am positive or negative for HIV

Hi Concernedline Thanks for getting in contact. The control line and the test line can only appear in the positions marked on the results reading pages of the instructions for use with a 4mm gap between them. Sometimes other marks can appear on the strip over time, particularly above the control line. These are not lines and do not indicate a positive result. From what you have described this is the case with your test. Also it is worth pointing out that the test should only be read at the 15 minute mark and not more than an hour after the test has been conducted. If you can take a picture of your test and email it to me ( I will confirm this. It would also be very handy if you could include your order number (from the order confirmation that you would have received) or the Lot number of the test from the pouch or the box. Thanks Kind regards Gary Carpenter BioSure (UK) Limited

I also just had what looked like a negative result. I had a very strong control line.... but directly above this. And when I say dirswctly I mean less then a MM above. There was a faint line. What is this? Is this a positive result?

Hi Worrier123 Thanks for getting in contact with us. The triggering of the control line (regardless of the intensity of the line) shows that you have collected enough sample for the test procedure to be valid. I hope that this helps to answer your question. Kind regards Gary Carpenter BioSure (UK) Limited
