what can make a1c falsely high

Several factors can cause a falsely high A1C result, including:

• Anemia: Conditions like iron-deficiency anemia or vitamin B12 deficiency can increase A1C levels.
• Kidney Disease: Impaired kidney function can affect red blood cell turnover, leading to higher A1C readings.
• Liver Disease: Liver conditions may alter hemoglobin metabolism, impacting A1C results.
• Blood Disorders: Sickle cell anemia or thalassemia can cause elevated A1C levels.
• Medications: Certain drugs, such as opioids or HIV medications, may interfere with A1C accuracy.
• Pregnancy: Hormonal changes during pregnancy can affect A1C levels.

If you suspect any of these factors apply to you, consult your healthcare provider for further evaluation and alternative testing methods.
