Ion Selective Electrodes or?


The ISE results are too damn high

Just in time for the daily morning draws, the ISE results start delta failing. Every patient. Dear God what did I screw up during maintenance.  Did I mismatch the reference solution? Did I not prime the new tubing well enough with pooled serum? The QC and calibrations were in though??? Ughh. More like Ion Selectively-working electrodes. 

 I think every chemistry instrument in existence is in a constant state of having the ion selective electrodes not working in some way or another. We should just start reporting semi-qualitatively. Probably low, Probably normal, probably high.
