The "r0" you are referring to is likely a typo and should be "Ro." The Ro subtype is a variation of the Rh positive blood type.
Understanding Rh Blood Types
Before discussing the Ro subtype specifically, it's helpful to understand Rh blood types in general.
- Rh Factor: The Rh factor is a protein found on the surface of red blood cells. If you have this protein, you are Rh-positive; if not, you are Rh-negative.
- Rh Positive: People with Rh-positive blood types can have either the RhD or Ro protein subtype.
- Rh Negative: People with Rh negative blood types do not have the D antigen or the Ro protein.
The Ro Subtype
The Ro subtype is one of many variations of Rh positive blood types. It's important to note:
- Not a Problem: According to the reference, having the Ro subtype does not indicate any issue with your blood. Everyone has a blood subtype, and it's simply one of the variations that make up your complete blood type.
- Found with Rh Positive Blood: You might have the Ro subtype if you have one of the following Rh positive blood types:
- O positive
- A positive
- B positive
- AB positive
Ro Subtype Details
The Ro subtype is one of the many variations within the Rh system. It is characterized by a specific combination of antigens. This subtype is determined by genetic inheritance and is just one of the many ways Rh antigens can be expressed in an individual.
| Blood Type | Rh Factor | Possible Subtype |
|---|---|---|
| O+ | Positive | Ro |
| A+ | Positive | Ro |
| B+ | Positive | Ro |
| AB+ | Positive | Ro |
Key Points
- The Ro subtype is a normal variation, not a medical concern.
- It exists only within the Rh-positive blood group.
- It's determined by your genes, just like your main blood type.
