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. After another two weeks, the urinalysis showed protein +/- again. A month later, 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 the urine is less than 150 mg/24h, it is referred to as proteinuria."Physiological increase refers to the recurrence of temporary proteinuria under certain physiological conditions without pathological changes. It is commonly seen 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 cases will never be excessively high.
The above suggestions are for the issue of "reappearance of 1+ protein in the urine test of the little girl." It is hoped that this will be helpful to you. Wishing you good health!"
