Unable to Determine
Your DNA file doesn't contain the necessary genetic markers for blood type analysis.
What You Can Do
While we couldn't determine your blood type from your DNA file, there are several reliable alternatives.
Clinical Blood Test
Visit your doctor or a local laboratory for a definitive blood type test. This is the most accurate method and takes only a few minutes.
Blood Donation
Consider donating blood at your local blood bank. They will test your blood type and inform you of the results � while helping save lives.
Alternative DNA Tests
Some DNA testing companies include blood type markers in their analysis. Consider uploading data from a different testing provider.
Global Blood Type Distribution
How blood types are distributed across the world's population.
| Blood Type | Percentage | Distribution |
|---|---|---|
| O+ | 38% | |
| A+ | 34% | |
| B+ | 9% | |
| AB+ | 3% | |
| O- | 7% | |
| A- | 6% | |
| B- | 2% | |
| AB- | 1% |
Key Statistics
- O+ is the most common blood type globally (38%)
- AB- is the rarest blood type (1%)
- About 85% of people have Rh-positive blood
- Type O is the "universal donor"
- Type AB is the "universal recipient"
Blood Type Compatibility
Understanding who can donate to whom is vital for medical emergencies.
"Diversity as continuity, not division � all blood types are variations within a shared humanity."
| Blood Type | Can Receive From | Can Donate To |
|---|---|---|
| AB+ | All blood types (Universal Recipient) | AB+ |
| AB- | A-, B-, AB-, O- | AB+, AB- |
| A+ | A+, A-, O+, O- | A+, AB+ |
| A- | A-, O- | A+, A-, AB+, AB- |
| B+ | B+, B-, O+, O- | B+, AB+ |
| B- | B-, O- | B+, B-, AB+, AB- |
| O+ | O+, O- | O+, A+, B+, AB+ |
| O- | O- only (Universal Donor) | All blood types |

Rh factor determination
The ABO System
The ABO blood group system classifies blood into four main types: A, B, AB, and O. These types are determined by the presence or absence of specific antigens on red blood cells. Discovered in 1901 by Karl Landsteiner, this system remains foundational to transfusion medicine.
The Rh Factor
The Rh factor (positive or negative) refers to the presence or absence of the RhD protein on red blood cells. Most people are Rh-positive (85%), while Rh-negative is less common globally but varies significantly by population and geographic region.
Health Recommendations
How to make the most of knowing your blood type.
Keep Record
