Hi Stef,
its been very long time since i posted in the forum. recently I tested for HBSAG (IU/ML measurement is not available as they stopped it) and I got the count as 6850 COI. Upon searching in google, i found that 1 COI is equivalent to .064 or 1 IU/ML = 18.21 COI. From this i am getting the IU/ML equivalent of 380-440 IU/ML.
is COI (ELISA method) method of calculation reliable?
Thanks
Raja
