Urine protein 2+ usually corresponds to 1.0~2.0g/L urine protein. However, the qualitative and quantitative results of urinary protein may not correspond exactly to each other, and it is recommended to analyze the results together with the actual condition.
Generally speaking, urinary protein (-) corresponds to <0.1g/L, urinary protein (±) corresponds to 0.1~0.2g/L, urinary protein (+) corresponds to 0.2~1.0g/L, urinary protein (++) corresponds to 1.0~2.0g/L, urinary protein (+++) corresponds to 2.0~4.0g/L, and urinary protein (++++) corresponds to >4.0g/L.
Negative and positive urine proteins are qualitative tests and need to be detected using dry chemistry, etc. How many g/L of urine protein belongs to the quantitative test, which needs to be detected using immunoturbidimetric assay, etc. Qualitative and quantitative tests have different experimental methods and different sensitivities to various types of proteins, so the results of the two tests may not correspond exactly to each other, and the results should be analyzed in conjunction with the disease condition and other comprehensive analysis.
If urinary protein 2+ is detected, it is recommended to go to a regular hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
