Causes and Treatments for Hemoglobin in Urine

Hemoglobin in the urine, scientifically called hemoglobinuria, occurs when red blood cells are destroyed and are eliminated by the urine, giving it a reddish and transparent color.

However, the presence of hemoglobin in the urine does not always cause symptoms and is only detected by chemical examination with a test strip or microscopic examination and should be treated as soon as possible by the urologist.

Hemoglobin in the urine can occur in children, adults and even in pregnancy, due to kidney infections, kidney stones or serious kidney diseases such as pyelonephritis or cancer, for example. Sometimes at the same time with hemoglobinuria hematuria occurs, which is urine with blood and it is necessary to go to the doctor to analyze the cause. Learn more at: Urine with blood.

How to Identify Hemoglobin in Urine

Hemoglobin in the urine is positive when, after chemical examination with a reagent strip, signs, traces or crosses appear on the strip and, negative when no changes occur.

Generally, the more traces or crosses are present on the strip, the greater the amount of blood in the urine. However, it is always necessary to read the instructions on the packaging of the reagent strips, since the analysis of the results depends on the laboratory of the reagent strips.

In addition to the strip test, a microscopic examination can also be done through a sediment scan, which detects the amount of blood present. In this case, it is considered normal to have less than 3 to 5 red cells per field or less than 10, 000 cells per ml. Learn more at: Urinalysis.

Symptoms of hemoglobin in urine
