Hematologic parameters in Thai subjects over 50 years old.
Advancing age is associated with the decline of hemoglobin, red blood cell count and other parameters. The conventional normal values of hematologic parameters established by all age populations may not be suitable for the elderly. This study determined the hematologic parameters of Thai subjects aged over 50 years by using a fully automated cell counter. No significant age-related variations of all parameters were found. The MCV of both sexes showed an upward trend at age over 70. The red blood cell count and hemoglobin levels in males were higher than females. These, however; were not significant alterations. These hematologic values should be useful for screening and clinical investigation of the elderly.
