Please explain the units - you use nmol/L and other labs use ng/mL? How do you convert from one to the other
The nmol/L unit is the on that all UK laboratories
have been instructed to move to if they are not already
using it - see
To convert nmol/L to ng/mL divide by a factor of 2.5.
e.g. Our result is 75 nmol/L would give 75/2.5 = 30 ng/mL
Do you do any other tests - for example serum calcium and iron studies direct to the public?
The only test we currenlty offer to the public is Vitamin D.
We may develop other services in the future but this will
depend on full consideration of ethical issues and also the
practicalities, as not everything is measurable on a blood
Thank you for my ultra clear test results. Could I just check - your results state that greater than 50nmol/l is normal. My understanding is that total 25-hydroxyvitamin D should be over 75 nmol/L.
deficiency historically is defined as a blood level below 25 nmol/L and many
quote this range. Scientific evidence is emerging that the optimal level for
general health may be higher than 50 nmol/L but we will stay
with this a the moment.
