What Blood Type Calculator does

This free online tool predicts a baby's possible blood types and Rh risk based on the ABO and Rh genotypes of both parents. It calculates probability percentages for each blood type and estimates the likelihood of Rh incompatibility, which is important during pregnancy. The interface presents two parent input sections with dropdown menus for blood type (A, B, AB, O) and Rh factor (Rh+, Rh-, Unknown), allowing users to see how genetic combinations determine inheritance patterns.

Step by step

How to use the SmartCalc Blood Type Calculator

  1. 1

    Select Parent 1's blood type from the A, B, AB, or O dropdown menu

  2. 2

    Choose Parent 1's Rh factor as Rh+, Rh-, or Unknown

  3. 3

    Select Parent 2's blood type from the A, B, AB, or O dropdown menu

  4. 4

    Choose Parent 2's Rh factor as Rh+, Rh-, or Unknown

  5. 5

    View the probability percentages for each possible blood type and Rh incompatibility risk

Is it right for you

Best for

Expectant parents or those planning pregnancy who want to understand genetic inheritance patterns and Rh compatibility risks for family planning discussions.

Limitations

  • Results are educational estimates based on population genetics, not medical diagnosis
  • Rh factor predictions use population estimates when set to Unknown
  • Does not replace professional medical advice for pregnancy decisions
Questions

Blood Type Calculator FAQ

Can this calculator determine the exact blood type of my baby?
No, it provides probability percentages for possible blood types based on parental genetics. The actual blood type depends on the specific genes each parent carries, which may not be fully known.
What does Rh incompatibility risk mean for pregnancy?
If an Rh-negative mother carries an Rh-positive baby, her body may produce antibodies that could affect future pregnancies. The calculator estimates this risk when both parents' Rh factors are specified.
How accurate are the probability percentages shown?
The percentages are based on established Mendelian genetics and population data. They represent likely outcomes but cannot guarantee a specific result for any individual pregnancy.
Do I need to know my exact genotype to use this tool?
No, you only need to know your blood type and Rh factor. The calculator uses standard genetic principles to estimate probabilities from the observable ABO and Rh phenotypes.
