The pH indicator used in the Buffering Solution would be specific for the desired pH range. If you see a blue color, the solution is in that fairly narrow range - chemistry at work. There is no requirement in the insert (or in standards that I'm aware of)  to check the pH by a method other than eyeballing the color.

In reading the package insert and other information, I found no need to be testing the pH, due to the blue indicator. I was curious what others were doing. Historically the facility I am at has tested the pH, as well as eyeballing the color. I was looking to remove testing the pH from our procedure if it is not necessary.

Does anyone that uses Immucor's Elu-Kit II test the pH of their eluate once it turns blue? Or do you just go by the blue color indicator as being within the appropriate pH range?
