summary

Last week I just had a holiday, so I accompanied one of my former classmates to have a physical examination. Recently, the physical examination report of that classmate came out. That classmate had proteinuria, so he decided to ask the doctor about it. Now let me talk about what proteinuria + - means.

What does proteinuria + - mean

First, according to the degree of turbidity, sedimentation and coagulation, determine the number of "+" (plus sign). The standard of judgment is: -: the minus sign is negative, indicating that there is no protein. After adding the reagent, the urine is still clear, and there is no turbid performance in the black background; "±": plus minus sign, which means there is trace protein in the urine. After the reagent is added, there will be white light turbidity, which can be seen only on the black background; "+": a plus sign, which means there is a medium amount of protein in the urine.

Second: after adding the reagent, white light turbidity, no flocculent particles appear; "+ +": two plus signs, representing the amount of protein in urine. After adding the reagent, obvious white precipitation appeared; "+ +": three plus signs, representing a large amount of protein in urine. After adding reagent, flocculent white precipitate appeared; "+ + +": 4 plus signs, representing a large amount of protein in urine.

Third: after adding the reagent, it immediately appears to solidify into a block, like peptone. According to the turbidity reaction, the content of urinary protein was estimated as follows: urinary protein < 0.1 g / L: -; urinary protein 0.1-0.2 g / L: ±; urinary protein 0.2-1.0 g / L: +; urinary protein 1.0-2.0 g / L: + + +; urinary protein 2.0-4.0 g / L: + + +; urinary protein > 4.0 g / L: + + + +.

matters needing attention

Because the increase in urinary protein is due to excessive protein intake diet, so in normal times should pay attention not to eat too high protein diet, the best is low protein food. We should have a physical examination every other period of time. If we find proteinuria, we should go to the doctor immediately.
