Effects of Storage at Room Temperature and at 4○C on Stability of Complete Blood Count Measurements

Abstract

The CBC is a basic screening test and one of the most frequently ordered laboratory procedures. The findings in the CBC give valuable diagnostic information about the hematologic and other body systems, prognosis, response to treatment, and recovery. The CBC consists of a series of tests that determine number, variety, percentage, concentrations, and quality of blood cells. CBC results varies by age, sex, race and demography During the first half of the 20th century, the CBC was performed using exclusively manual techniques. Manual counting methods are vulnerable to human mistakes that can easily result in errors. Furthermore manual counting is limited by the inherent error of imprecision. For more than 40 years; blood count parameters have been measured automatically. A variety of automated instruments for performing blood counts are in widespread use. The common fundamental counting principles include: i) electrical ii) optical light scattering iii) fluorescence.
