Sugar-water hemolysis test
.Sugar-Water Hemolysis Test
A sugar-water hemolysis test is a laboratory method used to check if a person's red blood cells are healthy and can withstand changes in their environment. It is a simple and quick method, which helps doctors determine the cause of any red blood cell health changes, and therefore can aid in the diagnosis and treatment of conditions in which red blood cell health is affected.
Preparation
A sugar-water hemolysis test involves the laboratory technician taking a sample of the person's blood and adding it to a solution of dextrose and water. The ratio for the solution should be 1 part dextrose and 2 parts water. The sample is incubated for approximately 30-60 minutes before the laboratory technician can observe any visible changes.
Procedure
Once the sample has been incubated, the laboratory technician can assess the sample for changes and can then compare it with a normal sample. If the sample shows any visible changes, such as a discoloration or change in texture, then it is said to be a positive result. However, if no visible changes are noticed, then the test result is simply reported as negative.
Types of Sugar-Water Hemolysis Test
- Indirect Sugar-Water Hemolysis Test: This is the most common type of sugar-water hemolysis test and is often used to assess red blood cell health conditions such as thalassemia.
- Direct Sugar-Water Hemolysis Test: This is a more specific type of sugar-water hemolysis test and is used to diagnose specific red blood cell health conditions such as sickle cell anemia.
Risks
There are no known risks associated with a sugar-water hemolysis test as it is a non-invasive and relatively low-risk procedure. However, it is possible that the sample may not be taken correctly, or that the laboratory technician may not be able to interpret the results accurately.
Why is it Done?
A sugar-water hemolysis test is done to assess the health of a person's red blood cells. This test helps doctors determine the cause of any red blood cell health changes and can therefore aid in the diagnosis and treatment of conditions in which red blood cell health is affected.
When is it Done?
A sugar-water hemolysis test is usually done when a doctor suspects a red blood cell related health condition, such as thalassemia or sickle cell anemia. It is often used to confirm or exclude such conditions.
