The normal indicator for 24-hour urine protein quantification is <150mg, if it is greater than this value it is called proteinuria. If the urine protein level is ≥3.5g/24h, it is called massive proteinuria.
The 24-hour urine protein quantification test is through the collection of all the urine within 24 hours as a specimen, the total amount of protein in the laboratory. 24-hour urine protein quantification of normal value <150mg, pre-pubescent girls in the urine protein discharge increased, 24-hour urine protein quantification can even reach 240mg is considered normal. If the urine protein content ≥ 3.5g/24h, it is called massive proteinuria.
Proteinuria is not always pathological, there are functional proteinuria and pathologic proteinuria.
Functional proteinuria, also known as physiological proteinuria, is most common in young people, under the influence of strenuous exercise, fever, mental stress and other factors, renal vascular spasm or congestion, resulting in increased permeability of the glomerular filtration membrane and protein leakage; pathologic proteinuria is commonly found in acute and chronic glomerulonephritis, cryptogenic nephritis, diabetic nephropathy, purpuric nephritis, renal arteriosclerosis, urinary tract infections, and so on.
If the 24-hour urine protein is abnormal, it is recommended to consult a regular hospital and standardize the treatment under the guidance of a physician.
