Hi everybody, im looking for a little help to decipher my recent blood test results, little background, unexplained weightloss, thinning and breaking hair, horizontal ridges in all nails (beaus lines i think), toe nails lifting away from nail bed, feeling tired almost hungover at some points and frequent brain fog, had 3 blood tests over the last 18 months, gps saying they've all come back fine, so saying as long as i dont keep on losing weight (was 9st 6lb dropped to 8st in around 12 months with no dietary or lifestyle changes) then im fine, latest blood test doc said very slight vitamin D drop so just take over the counter supplement, not severe enough to cause any symptoms. Now my issue is i cant see any results of vitamin D on the pages i got him to print out, but i think i may be low on folate, or is that vitamin D? My reading is 4.1 (ng/ml) i think that may be low ? My b12 is 346 (ng/L) my serum TSH level is 1.30 (mui/L) so hes said my thyroid is fine there are a few other results that seem to be on the low end but its so hard to fathom out google says so many different things !
