Anti-I?

Recommended Posts

We had an interesting case today. Patient is B pos with a neg Ab screen. ABO discrepancy in reverse (B cells 1+). Initial testing on Provue (gel). Repeated in tube, no discrepancy and Ab screen neg all 3 phases. Did 4 degree incubation, all 3 SCs pos with neg auto control. Two group O cord cells neg at 4 degrees. So I'm calling it an anti-I but all the other anti-I's I've seen we're auto anti-I's. Any other thoughts?

I should have mentioned that patient had similar results last visit.

Sounds like it could well be a very rare adult ii to me from your findings. They are about 0.01 to 0.03% of the population!

I would get this patient's blood checked out by a Reference Laboratory.

If it is, well done and get excited!!!!!!!!

Be aware that there is an association (no more than that) between adult ii and congenital cataracts amongst certain ethnicities.
