Abstract
During the period of about one year from Dec., 1965 through tact., 1966, the urine of 5684 cases in medical clinic were tested. The patient with positive result was followed up, and the cause of positive result was investigated.
It consists of 283 cases of proteinuria, 170 cases of glycosuria and 1243 cases of urobilinogenuria. Except the cases with already some disease or suspicious symptom, unexpected positive result, which contribute to diagnosis of unexpected disease, was found in 0-5% of proteinuria, 0-5% of glycosuria, 0-3% of urobilinogenuria respectively.
In this screening, it was recognized that unexpected protein and sugar may be a key for the diagnosis of hyperthyroidism and cystitis, However positive urobilinogen was not useful because of the unspecificity.
