Blood grouping and Rh typing is a laboratory test used to determine a person’s blood type (A, B, AB, or O) and Rh factor (positive or negative). The test is often done before a blood transfusion or before a woman becomes pregnant to check for compatibility with the blood of the person receiving the blood or the fetus.

Pre-test preparation: No special preparation is required for this test.

Testing method: The test is typically done using a sample of blood from a vein in the arm. The blood is mixed with special reagents that cause a reaction if certain blood antigens are present. The results of the test are then read and interpreted by a laboratory technician.

Common symptoms for prescribing this test: This test is typically ordered as part of a routine prenatal screening or before a blood transfusion. It may also be ordered if a person has a history of blood transfusions or if they have a certain medical condition that affects the blood.

Diagnosis: The test results will indicate the person’s blood type and Rh factor.

Reference range: The reference range for blood grouping and Rh typing will depend on the specific test being used.

Normal values: A person’s blood type can be A, B, AB, or O, and their Rh factor can be positive or negative. It is important to note that a person can have a different blood type than their biological parents.

It is important to consult with a doctor or healthcare professional for any questions or concerns regarding the Blood Type test or any other medical test
