Urinary phosphorus

The total amount of phosphorus in adults is 400-800g, accounting for about 1% of adult body weight, accounting for 1/4 of total minerals in the body. Among them, 80% to 85% together with calcium constitute a bone salt (hydroxyapatite [Ca2(PO4)2]3Ca(OH)2) involved in the formation of bones and teeth. The remaining 20% ​​is distributed in various soft tissues in the form of organophosphate compounds. Various biologically active substances such as proteins, nucleic acids, nucleotides, and phospholipids, which are composed of phosphoric acid, have a wide range of functions in the body. Only a small fraction of the phosphorus is present in the body fluid as an inorganic phosphate. The human body consumes 1.0 to 1.5 g of phosphorus per day, and the phosphorus that can be absorbed by the human body is an organic phosphate compound such as a phosphate ester or a phospholipid. Phosphorus is excreted by the intestines and kidneys, and the amount of renal excretion accounts for about 60% of the total excretion. 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: Found in parathyroidism, rickets, celiac disease, renal failure, nephritis with acidosis, increased sugar utilization. Normal value: Urine phosphorus (adult): 0.5-1.3g/24h Above normal: Found in hyperthyroidism, Fang syndrome, metabolic alkalosis and so on. negative: Positive: Tips: It is forbidden to exercise vigorously. The androgen, synthetic hormones and some diuretic drugs are stopped in the week before the examination. The alcohol is forbidden for 3 days before the examination, and the middle urine is taken for examination. Normal value Adult 0.5 ~ 1.3g / 24h. Clinical significance Abnormal results: Increased urinary phosphorus excretion: seen in hyperthyroidism, Fang syndrome, metabolic alkalosis, etc. Reduced urinary phosphorus excretion: seen in hypoparathyroidism, rickets, celiac disease, renal failure, nephritis with acidosis, increased sugar utilization, etc. People who need to be tested: hyperthyroidism, kidney failure, nephritis, weight loss. The result is low, may be disease: hyperparathyroidism results are high, may be disease: hyperthyroidism, hyperactivity Before the test: prohibit strenuous exercise, maintain a good diet and work schedule, stop androgen, synthetic hormones and some diuretic drugs one week before the test. Drink alcohol for 3 days before the test. At the time of examination: a part of the urine is discharged first to wash away the bacteria remaining in the urethra and the anterior urethra, and then the middle part of the urine is taken for inspection. Inspection process The urine of the subject was collected and detected by chemical methods. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally no complications and harm.
