Hello!

Was wondering what lab value other facilities use for Calcium replacement protocols. Ours currently tells RN to replace on either ionized Ca or corrected serum calcium.

However, RNs don't normally calculate corrected serum calcium and it seems ionized calcium is not something that's part of our main chemistry instruments in lab so testing isn't available (except we do get it in our ABGs).

What do other facilities use? Does anyone use serum calcium (not corrected)? I'd worry that we'd be prone to over correction if we did that...

Thanks!
