Hemoglobinuria test

What is Hemoglobinuria Test?

The Hemoglobinuria Test is a laboratory test used to evaluate the presence or absence of unconjugated bilirubin in the urine. Unconjugated bilirubin is a type of pigment that results from the breakdown of hemoglobin, which is found in red blood cells (RBCs). The test is usually performed to diagnose a condition called hemolytic anemia or to determine the source and extent of bleeding in the GI tract.

Preparation for the Test

No special preparation is required for Hemoglobinuria Test. However, if you are taking any medications such as antibiotics, antacids, or laxatives, tell your doctor beforehand, as these may affect the test results.

Procedure for Hemoglobinuria Test

The procedure for Hemoglobinuria Test is very simple and doesn't require any specific equipment. It usually involves collecting a sample of your urine in a sterile container and sending it to the laboratory for analysis. The results of the test are usually available within hours of collection.

Types of Hemoglobinuria Test

  • Urine Microscopy: A microscopic examination of urine to look for and see red blood cells that have been degraded into hemoglobin.
  • Urine Spectrophotometry: An analysis of a sample of urine with a device that reads different light spectrums which can identify the presence of unconjugated bilirubin in the urine.
  • Urine Immunoassay: A test in which a urine sample is tested with antibodies to measure the amount of unconjugated bilirubin in the urine.

Why is the Hemoglobinuria Test done?

The Hemoglobinuria Test is typically ordered when a doctor suspects that a patient has hemolytic anemia or an excessive amount of bleeding in the GI tract. It is performed to confirm the diagnosis and assess the severity of the anemia. Other conditions that may lead to hemoglobinuria can also be detected with this test.

When is the test done?

The Hemoglobinuria Test can be done at any time. It is typically performed when the patient has symptoms of hemolytic anemia or if they have experienced any abnormal bleeding in the GI tract. Additionally, the test may be ordered if the patient has had a recent blood transfusion, as this can increase the amount of unconjugated bilirubin in the urine.

Risks associated with Hemoglobinuria Test

The Hemoglobinuria Test is a simple and safe procedure that is not associated with any major risks. However, it is important to follow all instructions given by your doctor and laboratory technician when collecting the sample to ensure accurate results.
