An Addition of Boric Acid To Test The Number of Urine Cylinders

摘要

Urinalisa is a screening test to determine kidney disorders, urinary tract or metabolic disorders. Urinalysis must be done when the sample is still fresh. Delays in examinations will have a major effect on the stability of the test and the validity of the results of the examination. In the stages of urinalysis or other laboratory examinations, the biggest error lies in the pre-analytic stage, among others, is the handling of samples prior to examination. The existence of this case requires us to deal with the problem. The aim of this study is to determine the effect of urine treatment with additional additives on the number of cylinders. This study is an experimental experiment with an interpretive posttest control group conducted in May 2018, at the Clinical Laboratory Laboratory Dr. Sardjito. A total of 30 urine samples were divided into two groups, namely the control group and the experimental group. The control group only contained urine without the addition of boric acid, while the experimental group was given treatment in the form of addition of boric acid, the residence was carried out at 3 hours and 6 hours. Amount of cylinder urine was examined by Urine Analyzer Sysmex UF-500i. The results showed that the average number of slides decreased in delay for 3 and 6 hours in the chambers, both with boric acid addition and addition of boric acid. With the difference in 3 hours as much as 0.2 cells / μL higher the experiment and at 6 hours 0.3 cells / μL higher the control. The conclusions of this study are the effect of a number of urine cylinders which are resided within 3 hours and 6 hours at the temperature of the brain with the addition of boric acid.
