title: Intact PTH study: shipping frozen vs. unfrozen samples.
abstract: DCI Laboratory, Nashville TN compared INCSTAR N-tact PTH SP Kit (INCSTAR Corp., Stillwater, MN, USA) results from renal dialysis patients analyzed on frozen versus unfrozen samples; unfrozen samples were analyzed at 24, 48, and 72 hours post-collection. There was no statistical or clinical difference in the results of the frozen samples and unfrozen samples analyzed at 24 hours. Clinics may now ship unfrozen samples if they arrive within 24 hours.
