Abstract | <p><b>OBJECTIVE: </b>To define reference hematologic and biochemical lab values in older individuals.</p><p><b>DESIGN: </b>Randomly selected, age- and gender-stratified participants.</p><p><b>SETTING: </b>Visits by participants to four research clinics.</p><p><b>PATIENTS: </b>A total of 5201 participants in the Cardiovascular Health Study, an observational study of older Medicare-eligible individuals living at home.</p><p><b>MEASUREMENT: </b>Information about health status, previous illness, and medication use was obtained from participants and/or their MDs. This information was used to define a healthy subset of the population. Blood samples were obtained for Cholesterol, HDL and LDL cholesterol, fasting and 2-hour postload glucose and insulin, fibrinogen, factors VII and VIII, potassium, creatinine, albumin, uric acid, white blood count, hematocrit, hemoglobin, and platelet count.</p><p><b>RESULTS: </b>Significant differences were found for age group and/or gender for all mean values. Many tests were significantly different from the generally accepted reference ranges used in clinical laboratories.</p><p><b>CONCLUSIONS: </b>In some situations accepted laboratory norms for the general population can not be extrapolated to older adults. There are implications for both research and clinical practice.</p> |
