What is HbA1C?
HbA1c, also known as glycated hemoglobin, is the primary marker used in the HbA1c blood test, and helps measure the average blood glucose levels over the past two to three months. It is formed when glucose in the blood binds with hemoglobin, the protein responsible for transporting oxygen in red blood cells throughout the body.
Factors that affect HbA1c blood test results
Fluctuations in blood glucose levels during pregnancy can impact HbA1c results, in this case healthcare providers may use alternative methods to monitor glucose control in pregnant individuals with diabetes.
Furthermore, HbA1c levels can be affected by specific steroids and antiretroviral drugs, it is important to inform healthcare providers about all medications being taken to ensure accurate interpretation of test results.
Certain medical conditions such as anaemia or haemoglobin disorder can impact the results of the HbA1c blood test, often causing inaccurate readings. Similarly naturally occurring haemoglobin variants can cause inaccuracies in HbA1c blood test results, this is because they interfere with the binding of glucose to haemoglobin, resulting in values that may not reflect actual blood glucose levels, leading to higher or lower readings.
Symptoms of High HbA1c
- Unexplained weight loss
- Fatigue and weakness
- Slow wound healing
- Recurrent Infections
- Blurry Vision
- Tingling and Numbness
- Excessive Thirst
- Frequent Urination
Symptoms of Low HbA1c
Although less common then elevated levels, it is possible to experience low HbA1c levels.
- Headaches
- Confusion and irritability
- Dizziness and light-headedness
- Shakiness and sweating
- Hunger
- Rapid heartbeat
How do I lower HbA1c levels?
Lowering HbA1c levels involves a combination of different lifestyle adjustments, regular monitoring, and if prescribed, management of medication, there are some effective strategies available that can help you lower your Hba1c levels.
Managing Diabetes with a HbA1c Blood Test
Playing a significant role in diabetes management, the HbA1c blood test provides a reliable assessment of how well an individual’s diabetes is being managed over time. By monitoring long-term blood glucose levels, healthcare professionals use the test in order to identify any trends and make informed decisions regarding current or future treatment plans.
Do I need to prepare for a HbA1c blood test?
An HbA1c does not typically require extensive preparation, blood will be drawn either from a finger prick or a vein in your arm, and tested in our in-house laboratory. However, there are a few general guidelines that you can follow to ensure accurate results:
Always inform your doctor.
Follow Instructions.
Hydrate regularly.
Fasting is not required.
Continue medications and supplements, unless directed.
How frequently should the HbA1c blood test be taken?
An individuals’ personal diabetes management plan will determine how frequent the hba1c blood test should be taken. For those with well-controlled diabetes, your doctor may advise testing every three to six months, however, those with suboptimal glycemic control, or undergoing treatment adjustments, may need testing more often.
