Sample Stability

The following tables show the average results for specimens from five normal donors
collected in K
For this study, room temperature was 72 - 73º (22 - 23ºC) and cold temperature was 37 - 39ºF
(3 - 4ºC). Room temperature specimens were mixed for 22 inversions and then immediately
analyzed. Upon removal from the refrigerator, the cold specimens were mixed for 22
complete inversions and analyzed within five minutes
