HiI'm rather slow on the uptake these days, but after a failed iron profile pinprick, which I knew wouldn't work as blood was thick & not flowing,just had a thought!
Buy some alcohol wipes! Once I've used one supplied, feel have to plod on with test. Whereas with more wipes, after 1 pinprick if its not looking good, will not complete test, just try again next day! I have a fair few pinprick stabber things, presume they don't go.out of date? So can give it a good few tries.
Had so many failed iron panels last yr, but miraculously got 1 to work couple months back, only needed 1 pricked finger that day & blood flowed well, so that's obviously the answer with that test.
The thyroid ones thankfully seem to work, even if I've pricked 4 fingers. I follow everything the same.
If I tackle it with wipes a plenty I'm bound to hit on a good day eventually🤣
