Abstract
A urine specimen is preserved from bacterial deterioration as to relative constituents by adding thymol. To the thymol-treated specimen, lithium-solution volume-marker is added, then is divided into two (first and second) separate portions. Thereupon, using the first portion, standard conventional measurements and/or analysis is conducted for total volume, pH/acidity, uric acid, citrate, sodium, and potassium. To the second portion, there is added boric acid and hydrochloric acid, followed by standard/conventional measurement and/or analysis for ammonium ion, citrate, calcium, magnesium, phosphorus, oxalate and sulfate. Thereafter the findings are charted and compared to controls.
