Blood Type Test in Puerto Rico

A blood type test identifies your ABO blood group and Rh factor. It is commonly ordered before transfusions, during pregnancy, or for organ donation.

What it measures

ABO group — Determines if you are type A, B, AB, or O based on markers on red blood cells.
Rh factor — Shows whether you are Rh-positive or Rh-negative, an inherited protein on red blood cells.
Antibody screen — Sometimes included to check for unexpected antibodies against other blood types.

Who it is for

A doctor may order this test before surgery, blood transfusion, pregnancy, or organ transplant. It is also done for donation or if you want to know your blood type.

Preparation

No fasting or special preparation is needed. You can eat and drink normally before the blood draw.

Results and what they mean

Results are reported as your ABO type and Rh status, such as A-positive or O-negative. A clinician interprets the results in your medical context. This is general information, not medical advice.
