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. However, 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 the urine is below 150 mg/24h, it is referred to as proteinuria.?"Physiological increase refers to the temporary recurrence of increased proteinuria under certain physiological conditions without pathological changes. This 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 "the 7-year-old girl's urine test showing protein again as 1+". It is hoped that this will be helpful to you. Wishing you good health!
