Was my test valid?

Hi there, I ran the Biosure test a few days ago and after reading the instructions and using the safety lance I couldn’t get enough blood in to the tube. I realised that hadn’t squeezed out enough blood to start with but when I managed to get a decent drop on my finger the tube would not suck up any more than it initially had. I would say that only about a third of the tube had blood in it and it looked like it was just coating the walls rather than filling the tube. I ran the test anyway and saw a clear control line and no others. Would this be a valid test even though I didn’t get the required amount of blood in the tube?

Thanks for clearing that up Gary. It's a relief knowing that I do not need to test again.

Hi RM and AB Having re-read AB initial post I have to apologise and clear up an error on my part. I misread AB's post. I thought that AB had said he didn't see a control line. The control line is calibrated to the test line, so that if the control line triggers then sufficient sample has been collected to make the test work. I hope that this helps to put your mind at rest and really sorry for the confusion. Kind regards Gary Carpenter BioSure (UK) Limited

Hi there, This also happened to me - negative result with control line clearly visible although tip was only about a third fill also. Even though I squeezed to get a sizeable drop on my finger, the tip didn't absorb it and after I had touched it off my skin the first time it wouldn't absorb any more after that. Does this mean the test has not worked? If so, your documentation is slightly misleading as it states that once the control line is there the test has worked correctly.

Hi AB Unfortunately it does sound as if you haven't collected enough sample to be certain. The negative result is very encouraging but you shouldn't consider the result conclusive. If you can email your order number to I will email you directly with regard to replacing the test. Kind regards Gary Carpenter BioSure (UK) Limited
