Do urine test strips detect red blood cells and free hemoglobin in urine?

The Urinox dipstick tests are designed to detect both intact Red Blood Cells (RBCs) and free hemoglobin (as well as myoglobin) in urine. Here’s how it works:

Intact Red Blood Cells (RBCs): When intact RBCs are present in the urine, they break down and react with the blood test pad on the dipstick. This reaction typically results in green spots appearing on a yellow or orange background. The number and concentration of these green spots usually correspond to the number of RBCs in the urine.

Free Hemoglobin and Myoglobin: If free hemoglobin or myoglobin is present in the urine, the test pad will produce a uniform green color or a green to dark blue color across the pad. This uniform color indicates the presence of these proteins in the urine.

If you notice green spots or a uniform green color on the reagent pad for blood, it’s important to consult with a physician. These findings could indicate the presence of blood or hemoglobin in your urine, which may require further investigation and professional diagnosis to determine the underlying cause.
