Which ALK is Right?

fishnugget1 · Jan 25, 2020

My Hannah with new reagent says 8.3.
My Salifert that expires in 6/2022 says 8.9

I have always used Hannah but I just wanted to check.

Which is right?

My Ipinion:
Both tests are both right and wrong. Variances in how each person tests and the chemicals we use are only so good. The most important part is that we are close and remain consistent.

+1 on consistency versus absolute accuracy. I'd probably post an 8.6 value into my records.
