Why Anaemia May Affect What Your HbA1c Test Shows
HbA1c is a blood test that gives an estimate of a person’s average blood sugar.
It usually reflects the previous two to three months.
The test relies on red blood cells.
These cells carry information that helps produce the HbA1c result.
Anaemia is a condition that affects the blood.
It may also affect red blood cells or how long they stay in the body.
Because of this, anaemia could make an HbA1c result harder to interpret.
People should ask a health practitioner how their health conditions may affect their test results.
HbA1c is commonly used to estimate average blood glucose over two to three months.
The test helps assess diabetes risk and monitor glucose control.
HbA1c depends on red blood cells and how long they remain in circulation.
Anaemia affects the blood and could influence how an HbA1c result is interpreted.
The article does not specify how anaemia changes HbA1c results or by how much.
