Phenol red excretion test

The phenol red excretion test (PSP) is a function to determine the excretion of dyes in the kidney. Phenol red is non-toxic and non-irritating to the human body, even for diseased kidneys. PSP excretion in the 15 minutes after adult injection was 28% to 51%, with an average of 35%; total excretion in 2 hours was 63% to 84%, with an average of 70%, and PSP excretion in children within 15 minutes was 25% to 45%; 2 hours excretion total 2 to 8 years old 60% to 75%; 8 to 14 years old 50% to 75%. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Chronic glomerulonephritis, chronic pyelonephritis, renal vascular sclerosis, Fanconi syndrome, heart failure, shock, severe edema, late pregnancy, urinary tract obstruction, bladder urinary insufficiency, etc. Normal value: PSP excretion (15 minutes after adult injection PSP): 28-51% PSP excretion (modeling? 3-84%) Above normal: No clinical significance. negative: Positive: Tips: Patients should drink 300-400 ml 30 minutes before intravenous phenol red to facilitate urination. Normal value The PSP excretion in the 15 minutes after the adult injection was 28% to 51%, with an average of 35%; the total excretion in the 2 hours was 63% to 84%, with an average of 70%. PSP excretion in children within 15 minutes is 25% to 45%; 2 hours excretion total 2 to 8 years old 60% to 75%; 8 to 14 years old 50% to 75%. Clinical significance When the renal tubular function was damaged by 0.50 (50%), there was a decrease in the PSP excretion rate. Reduction: chronic glomerulonephritis, chronic pyelonephritis, renal vascular sclerosis, Fanconi syndrome, heart failure, shock, severe edema, late pregnancy, urinary tract obstruction, bladder urinary insufficiency, etc. Low results may be diseases: chronic glomerulonephritis, chronic pyelonephritis, urinary tract obstruction Note before inspection: 1, the patient should drink 300 ~ 400 ml 30 minutes before intravenous injection of phenol red, in order to facilitate urination. 2. Do not drink diuretic beverages such as tea or coffee before and during the test. It is forbidden to phenolphthalein, mountain road, etc., which may cause color reaction and affect the result. In addition, aspirin, phenylbutazone, penicillin, etc. can competitively block phenol red into the renal tubules, so that the phenol red excretion is reduced, should also be banned. Requirements for inspection: After draining the residual urine in the bladder 20 minutes after drinking, intravenously inject 1 ml of 0.5% phenol red. Inspection process The patient drank 300-400 ml of water 30 minutes before the intravenous injection of phenol red to facilitate urination. After draining the residual urine in the bladder 20 minutes after drinking water, intravenously inject 0.5% phenol red 1 ml (do not let the liquid leak out, and record the time), and leave urine at 15 minutes, 30 minutes, 60 minutes, 120 minutes after intravenous injection. In the specimen bottle with the mark, and record the amount of urine, the time required to stay in the urine should be accurate. Every time the urine must be drained, it is sent to the test immediately. Not suitable for the crowd no. Adverse reactions and risks no.
