Patient's question:
After catching a cold, tonsillitis occurred. Urinalysis showed 3+ again. As the respiratory tract inflammation healed on its own, the urinalysis returned to normal. Two weeks later, the urinalysis was normal again. Then two weeks later, the urinalysis showed protein +/- again. After one month, fever and sore throat symptoms reappeared, and the urinalysis showed protein...Doctor's answer:
In normal urine, only trace amounts of protein are present. When the protein content in urine is less than 150 mg/24h, it is referred to as proteinuria.?"Physiological increase refers to the recurrence of transient proteinuria under certain physiological conditions without pathological changes. It is commonly observed after intense exercise (exercise-induced proteinuria), changes in body position (postural proteinuria), sudden exposure to extreme temperatures, or emotional excitement. In these cases, the endothelial cells of the glomeruli contract or become congested, increasing the permeability of the glomeruli. The protein quantification in such physiological conditions will never be excessively high.
The above suggestions are for the question "The 7-year-old girl's urine test shows proteinuria again (1+)." It is hoped that this will be helpful to you. Wishing you good health!
