How Do I Get My Blood Type From 23andMe Raw Data?


Larry Thompson

Have you recently received your genetic raw data from 23andMe and are wondering how to find out your blood type? Look no further! In this tutorial, we will guide you through the process of extracting your blood type information from your 23andMe raw data.

Understanding Blood Types

Before we dive into the steps, let’s quickly recap what blood types are and why they matter. Human blood is classified into four major types: A, B, AB, and O.

These blood types are determined by the presence or absence of certain molecules called antigens on the surface of red blood cells. Additionally, blood is also categorized by the presence or absence of a protein called Rh factor, resulting in either a positive (+) or negative (-) designation.

Accessing Your 23andMe Raw Data

The first step is to locate and download your raw genetic data from 23andMe. To do this:

  1. Login to your 23andMe account.
  2. Navigate to the “Tools” section in the main menu.
  3. Select “Browse Raw Data.”
  4. Click on “Download” to save your raw data onto your computer.

Analyzing Your Raw Data

Now that you have downloaded your raw data file, it’s time to analyze it for information related to your blood type. Follow these steps:

Step 1: Open Your Raw Data File

To open the downloaded file, locate it on your computer and double-click on it. This will typically open it in a text editor like Notepad or TextEdit.

Step 2: Search for Blood Type Markers

Inside the raw data file, use the search function (usually Ctrl+F or Command+F) to look for specific markers related to blood type:

  • rs8176746: This marker indicates your ABO blood group.
  • rs5030655: This marker determines your Rh factor (+/-).

Step 3: Interpret the Results

Once you have located these markers in your raw data file, you will see a combination of letters and numbers. Here’s how to interpret the results:

  • If “AA” is present at rs8176746, it means you have blood type A.
  • If “GG” is present at rs8176746, it means you have blood type B.
  • If “AG” is present at rs8176746, it means you have blood type AB.
  • If “GG” is present at rs5030655, it means you are Rh positive (+).
  • If “TT” is present at rs5030655, it means you are Rh negative (-).

Consulting a Healthcare Professional

While this method provides a reliable way to determine your blood type from your genetic data, it’s important to note that self-analysis may not always be as accurate as professional testing. If you require precise information about your blood type for medical reasons or personal curiosity, we recommend consulting with a healthcare professional or getting a blood test done.

In conclusion, by analyzing specific markers in your downloaded raw data file from 23andMe, you can determine your blood type and Rh factor. Remember to consult a healthcare professional if you require accurate and up-to-date information about your blood type.
