What this test is

This panel includes tests that determine your ABO and Rh blood type and may also assess for blood disorders such as anemia, clotting problems, or abnormal blood cell counts. It is not a single test but a group of tests that can be selected based on your needs.

What it measures

  • ABO blood group — determines if you have type A, B, AB, or O blood
  • Rh factor — indicates whether you are Rh-positive or Rh-negative
  • Hemoglobin — reflects the oxygen-carrying capacity of your blood
  • Hematocrit — measures the proportion of red blood cells in your blood
  • Platelet count — assesses clotting ability and risk of bleeding
  • White blood cell count — indicates immune system activity or potential infection

What the test involves

A standard blood draw from a vein in your arm is used to collect the sample. The sample is then analyzed in a laboratory to determine your blood type and evaluate blood cell characteristics.

Why it is often ordered

A clinician may order blood typing before a transfusion, during pregnancy, or before surgery. Blood disorder tests are often used to investigate symptoms like fatigue, weakness, easy bruising, or abnormal bleeding.

Preparation

Preparation depends on the specific tests included; some may require fasting or avoiding certain medications. Always follow the instructions provided by the collection lab.

How results are reported

Results are typically reported as your blood type (e.g., A positive) and numerical values for blood cell counts or other markers. Reference ranges vary by laboratory and are provided with your report.
