    Because you're drawing a tiny amount of blood from a low blood flow area. Theres also the accuracy of the punch hole.

    The effect of hematocrit and punch location on assay bias during quantitative bioanalysis of dried blood spot samples

    https://www.future-science.com/doi/abs/10.4155/bio.11.220

    The analysis of dried blood spot samples using liquid chromatography tandem mass spectrometry

    https://www.sciencedirect.com/science/article/pii/S000991201000302


    The finger prick tests always seem to over report prolactin and under report test, e2 etc.

    Their IV tests are dodgy somwtimes as well. When I get bloods I go to a nuffield, they draw and I get results that day. I decided to try the cheaper IV option from medichecks, came back all over the place. Complained to nuffield, they redid bloods for free and they were almost carbon copy as nothing had changed protocol wise or lifestyle. Dunno if they just let stuff sit for days on end in packages and there is degredation or if they're doing thag many tests its just being fucked up.

    Relax man, I’m just pulling your plumbs

    I asked for an explanation, you gave one

    When you say they over report prolactin and under report test e2, on what are you basing that on?

    First link is about hct, not hormones, your second link didn’t work for me mate

    Its the same principle, they use the same sampling method for everything on the testing. Pick a hormone plus blood spot test or something like that, the study will list the issues with present accuracy and the inconsistencies between sites. The tests also carry a +/-15% variance that they try to meet, it can often be missed by human error handling the blot paper and the end user not providing enough blood in the spot etc.

    I only get bloods pulled on test only. As soon as you have anything else added you need sensitive testing done and its double the costs which i can't afford to do everytime.

    The finger prick tests will be the biggest earner for them. Cheapest to produce, handle and test. They're however the most innacurate using current tech.

    Try one test just as you are no prep, right hand, clip and drip a bit blood. Get another test, have a bath, index finger left hand, get a good deep bleed into the test. Send both away and see what the difference is in the results minutes apart

    Ano in simple terms when I check my blood sugars in the house you prick your finger then dab it on a strip and straight into the machine , where as with the test yesterday it was with a syringe then connect to a test tube let it fill with blood then disconnect ,the tube has a preservative in the bottom you need to turn the tube upside down 10x to let it mix to stop the blood going off on the way to the lab, so a take it if you do a finger test in the post it's dried blood ?

    No it doesn't dry out. You drop about a mls worth of blood into a vial with a preservative in the same way. You've just drawn from a vein.
    I have no issues with blood flow from a finger prick test.
    Also when you donate they do a finger prick test to test for iron levels.

    I think ukm have started the whole finger prick tests are worthless rumours, based on fact certain labs didn't do so well in hormone levels. However knowing the greater picture and the motives behind, of course you're going to post unfavourable blood tests (probably screwed) if you're a reseller for a diff lab.

    They’ll always be slight variation between tests even if they were took minutes apart no?

    The way to go would be draw from vein and finger then send off, if it’s massively different then it would prove your point I guess

    If it’s just slight variation then I don’t think it’s anything to worry about is it

    You get lh pulses every 20 mins or so iirc

    stuff can yeah but not enough within the space of a few minutes to cause a significant swing that you often see with the test. If you're going to use the prick tests, do the bath thing and then get as much blood into the test as you can. bigger the sample with "fresher" blood will help reduce margins of error on the testing. if anything comes back way out of wack and its not expected, get a venous test done to verify

    Even with the finger prick tests I still just a a needle and syringe and draw from the vein. Takes too long trying to squeeze drops out your finger.
    Impressed you manage to draw blood yourself using the kit they provide. I tried it, but just couldnt get comfortable enough to do it.
