Total protein Albumin

Age- and sex-related “normal ” values were calculated for data obtained by screening 8015 patients ’ sera with the Technicon SMA 12/60 at the time of hospital admission. Calcium, phosphorus, total protein, and al-bumin concentrations decrease with age; glucose, urea nitrogen, choles-terol, and lactic dehydrogenase concentrations increase. Uric acid con-centration increases with age in women. Mean values for calcium, glucose, urea nitrogen, and uric acid concentrations are greater in men. Serum glutamic-oxaloacetic acid transaminase activity is most frequently ab-normal, total protein concentration least frequently. Alkaline phosphatase and bilirubin results were unremarkable. BIOCHEMICAL SCREENING HAS become increasingly prevalent since the advent of multichannel automatic analyzers (1, 2). The large masses of data that consequently accumulate can only be interpreted by knowing the values to be expecte
