The protein test on dipsticks is most sensitive to which protein?

Explanation:
The dipstick protein assay is designed to detect albumin most readily. The dye on the dipstick’s pad is optimized to bind albumin, producing a visible color change even at low concentrations. Other urinary proteins, such as hemoglobin or various globulins, don’t interact with the dye as efficiently, so they produce little to no color change at typical concentrations. This makes albumin the protein the test is most sensitive to, which is why dipstick testing is used as a screening tool for albuminuria and early glomerular disease.
