Match the blood group result you need to the test

Each of these answers a different blood typing question — ABO, Rh, or both together.

Only need the A, B, AB, or O part? the ABO classification on its own, without an Rh result View ABO Group $49 $39
Need weak D looked at rather than routine Rh? named for weak D testing, a narrower question than a routine Rh result View Rh, Weak D (DU) $74 $59

A blood type test identifies the ABO group, such as A, B, AB, or O, and/or the Rh type, commonly described as positive or negative. People compare these options when they need both results, only one of them, or clarification of an Rh finding. Know Your Blood Type measures ABO Group and Rh Type together. ABO Group and Rh Typing isolate one result when a request calls for that specific measurement. Start by determining whether you need the combined ABO and Rh result or a focused result already requested by a healthcare professional.

What ABO Group and Rh Type tell you

ABO Group classifies blood as A, B, AB, or O. Rh Type identifies whether the Rh result is positive or negative. These are separate blood-group characteristics, so a request for a full blood type commonly needs both measurements. Know Your Blood Type reports ABO Group and Rh Type together, while ABO Group and Rh Typing report one part of that pairing. Blood-group results are especially relevant when records are being established for transfusion-related discussions or pregnancy planning. A laboratory result should be reviewed with the clinician or facility requesting it when it will inform medical care.

When a focused Rh result is the better match

Rh Typing measures Rh Type, making it a direct choice when the requested information is Rh positive or Rh negative. Rh, Weak D (DU) is named for weak D testing, a more specific question than routine Rh Type reporting. Weak D questions can arise when an Rh result requires further characterization; interpretation matters because blood-product and pregnancy-related decisions use established clinical protocols. ABO Group does not supply Rh Type, and Rh Typing does not supply an ABO classification. Matching the order to the requested result avoids treating two distinct blood-group measurements as interchangeable.

Blood Type FAQ

A blood type test identifies ABO Group, Rh Type, or both, depending on the selected test. ABO Group classifies blood as A, B, AB, or O, while Rh Type reports the Rh result as positive or negative. Know Your Blood Type measures both ABO Group and Rh Type, giving the paired information commonly meant by a complete blood type.

ABO Group and Rh Type describe two different blood-group characteristics. ABO Group determines whether the classification is A, B, AB, or O; Rh Type determines whether the result is positive or negative. A person can have either Rh result within an ABO classification, which is why a full blood type result requires both pieces of information.

Know Your Blood Type reports both ABO Group and Rh Type. It fits a request for the familiar combined blood type, such as an ABO letter group paired with positive or negative Rh status. ABO Group and Rh Typing are narrower options that report only the named component rather than the complete paired result.

Select ABO Group when the requested result is limited to the A, B, AB, or O classification. Know Your Blood Type is the appropriate match when the request also needs Rh Type, reported as positive or negative. The practical difference is whether the result includes one blood-group characteristic or the ABO and Rh pairing.

Rh Typing measures Rh Type, the positive or negative portion of a commonly stated blood type. It does not provide the A, B, AB, or O classification, because that is the ABO Group result. This focused option is useful when an existing request specifically calls for Rh status rather than a combined ABO and Rh result.

Rh, Weak D (DU) addresses a weak D question, which is more specific than obtaining a standard positive or negative Rh Type result. It is relevant when further characterization of an Rh finding has been requested. Because weak D interpretation can affect transfusion-related or pregnancy-related planning, use the requesting clinician or care team to interpret the result.

No. ABO Group and Rh Type identify blood-group characteristics; they do not diagnose disease or explain symptoms. Their importance is tied to matching and planning discussions in settings such as transfusion care and pregnancy. Symptoms, prior reactions, or a complex medical history need professional evaluation beyond a blood-group result.

A prior record, memory, or nonclinical source is not the same as a current laboratory report. ABO Group and Rh Type are distinct results, and an incomplete record might state only one of them. When a blood type is needed for a medical decision, the requesting facility or clinician should determine what confirmation and interpretation are appropriate.
