Do You Know Your Blood Type? ABO Grouping & Rh Factor Test

Many people don’t — but knowing your blood group and Rh factor could be life-saving. It plays a vital role in emergency transfusions, pregnancy care, and surgical planning.

At Marylebone Diagnostic Centre, we offer fast, accurate blood group and Rh factor test in London with no referral required. Our central London clinic is conveniently located at 73 Baker Street, near Paddington and Marylebone.

What Is ABO Blood Grouping?

The ABO blood grouping system divides blood into four types:

• Group A
• Group B
• Group AB
• Group O

This classification depends on the presence or absence of A and B antigens on your red blood cells. Your blood group and Rh factor are essential for:

• Blood transfusions
• Organ donations
• Childbirth planning
• Health risk profiling (certain diseases may correlate with specific blood types)
• Emergency medical care

Knowing your blood group and Rh factor ensures the right care when it matters most.

What Is the Rh Factor?

The Rh factor is another protein that may or may not be present on your red blood cells:

• Rh-positive means the protein is present
• Rh-negative means it’s absent

Examples of full blood types include:

• A+ (A positive)
• B− (B negative)
• O+ (O positive)
• AB− (AB negative)

Why Rh Factor Is Crucial in Pregnancy

For expectant mothers, Rh compatibility is vital. If an Rh-negative mother carries an Rh-positive baby, it may trigger her immune system to attack the baby’s red blood cells — a condition known as Rh incompatibility.

This risk can be prevented with a simple injection of anti-D immunoglobulin, but only if detected early through a blood group and Rh factor test.

See NHS guidance on Rh incompatibility for full details.

When Should You Get a Blood Group & Rh Test?

Consider testing if you:

• Have never been told your blood type
• Are planning to conceive
• Recently moved to the UK and don’t have a complete medical history
• Are building a personal health record
• Want to donate blood – see NHS Blood Donation
• Are curious about potential links between blood type and health risks

💡 Remember: Even though blood type isn’t linked to all health conditions, awareness saves lives. Public figures like Deborah James highlighted the power of early action and understanding your health status. Read her story on Bowelbabe.com.
