pH (Dip , Urine)

 
Specimen / Container (สิ่งส่งตรวจ/ภาชนะ):
Urine/ Clean container 20 mL
 
Turnaround Time (ระยะเวลารอผล):
Collected specimen to report within 1 hour
 
Useful For (ประโยชน์การทดสอบ):
Urine pH is a crude measure of the acid-base balance of the body. It may be helpful in determination of renal tubular disease or pyelonephritis. Urine pH is useful for identification of crystals in urine and determination of predisposition to formation of a given type of stone. Control of urinary pH is important in management of nephrolithiasis.
 
Methodology (วิธีการทดสอบ):
This test contains a mixed indicatoe which assures a marked change in color between pH 5 and pH 9. Colors range from orange thought yellow and green to cyan.

Clinical Information (ข้อมูลทางคลินิก):
Dietary factors affect urine pH. Alkaline urine is observed in persons who eat large quantities of citrus fruit and vegetables. Acid urine is observed with high meat intake. Pyridium® metabolites may mask the pH reaction. Urine pH >6.5 indicates presence of bicarbonate while pH <5.5 indicates absence of bicarbonate. Consistently acid urine, pH <5.5, is associated with xanthine, cystine, and uric acid stones. Calcium oxalate and apatite stones are not associated with any particular disturbance of urine pH. Alkaline urine (pH >7) is associated with calcium carbonate, calcium phosphate, and especially magnesium ammonium phosphate stones. In conjunction with serum pH and bicarbonate levels, urine pH may be applied to the study of renal tubular acidification.
