Blood Type & Blood Disorders
This page explains the blood type & blood disorders, what it measures, and how to order it. This test identifies your blood type and can screen for certain blood disorders. It is useful for transfusions, pregnancy, and understanding your health.
What this test is
Blood typing determines the ABO and Rh blood groups, essential for safe blood transfusions and organ transplants. It can also detect abnormalities in red blood cells, white blood cells, or platelets.
What it measures
- ABO Blood Group — determines your primary blood type (A, B, AB, or O)
- Rh Factor — indicates if you are Rh-positive or Rh-negative
- Complete Blood Count (CBC) — evaluates the number and characteristics of red blood cells, white blood cells, and platelets
- Hemoglobin — measures the oxygen-carrying protein in red blood cells
- Hematocrit — measures the proportion of red blood cells to the total blood volume
What the test involves
A small sample of your blood is collected by a trained professional during a standard venipuncture procedure. The blood is then sent to a laboratory for analysis.
Why it is often ordered
Clinicians often order blood typing before surgeries or transfusions to ensure compatibility. Screening for blood disorders helps diagnose conditions affecting blood cell production or function.
Preparation
No special preparation is typically needed for this test. Always follow any specific instructions provided by the laboratory where you will have your blood drawn.
How results are reported
Results are typically reported within a few business days and will indicate your blood type and any detected abnormalities. Reference ranges for specific markers can vary between laboratories.

Common blood disorders include anemia (low red blood cell count), leukemia (cancer of blood-forming tissues), and hemophilia (a bleeding disorder).
Can this test detect all blood disorders?
This test can screen for many common blood disorders and abnormalities. However, some rarer or more specific conditions may require additional specialized testing.
How is my blood sample collected?
