thank you! ah yes, you were deficient. details:
quoting zinc result - serum zinc 75 ug/dL, range 56-134, detection limit = 5
the zinc bit from my reply: general-discussion-f1/topic21690.html#p204841
"zinc is deficient by WHO standards. you want to be much much further up the normal range."
in more detail, when we convert your 75 result that's 11.48 umol/L. WHO 'normal' range is 11.5-18.5 umol/L. you should have been flagged as deficient or at very least, borderline.
your lab's 'normal' range, 56-134, converts to 8.57-20.52 umol/L. everyone who goes to your lab and tests between 8.57-11.5 (56-76) is deficient by WHO standards. regardless, the lab readout reassures them they are inside the printed range, which is erroneously understood as 'normal' or 'okay'.
glad you are supplementing now! go have a beer to celebrate
