The effect of drinking habits on the frequency distributions of eight biochemical or haematological test results was studied in 7915 patients attending a multiphasic health testing centre. Increasing incidences of abnormal results with increasing alcohol intake, at levels of alcohol intake habitual for a large proportion of the population, were found for plasma gamma-glutamyl transpeptidase, triglycerides and uric acid, and for erythrocyte mean corpuscular volume. Of four frequently used liver function tests, aspartate aminotransferase, alkaline phosphatase, bilirubin, and albumin, only aspartate aminotransferase was strongly affected by drinking habits. These findings have relevance for the detection of individuals whose drinking habits are harmful to them, and for the interpretation of ‘profile’ results.
