Caffeine monitoring in infants: comparison of automated (VITROS 5, 1 FS) chemistry system versus HPLC analysis.

This is the first study comparing the caffeine testing by HPLC to the MicroTip Technology patented by Ortho-Clinical Diagnostics. For the determination of the precision for intra-run and day to day variances, control materials with concentration ranges between 2.3 microg/mL and 23.
