HbA1c Test in Jaipur
The HbA1c test, also known as the Haemoglobin A1c, glycosylated haemoglobin or Glycated Haemoglobin test, is a vital blood test that indicates how effectively your blood sugar is controlled and or diabetes is managed. It is generally used to determine the three-month average blood sugar level as the average lifespan of a red blood cell is three to four months. It can be used as a diagnose Type 1 and Type 2 diabetes.Higher levels of glycated haemoglobin in diabetics suggest worse management of blood glucose levels, which is linked to complications like cardiovascular disease, nephropathy, neuropathy, retinopathy etc.
About Diabetes mellitus
Diabetes mellitus is common in India, and the incidence is rising at an alarming rate. Diabetes is anticipated to rise from 40.6 million in 2006 to 79.4 million by 2030 in India alone. According to studies, the incidence of diabetes in urban Indian people is around 12.1%, with start occurring almost a decade sooner than in western equivalents, and the prevalence of Type 2 diabetes is 4-6 times greater in urban than in rural settings. High family aggregation, central obesity, insulin resistance, and lifestyle changes related to urbanization are all risk factors for developing diabetes among Indians.
Frequently Asked Questions
To diagnose diabetes, to monitor a person's diabetes and to aid in treatment decisions. It can also be used to diagnose type 2 diabetes.
Testing for diabetes or prediabetes(As per recommendation from CDC):
Get a baseline A1C test if you’re an adult over age 45—or if you’re under 45, are overweight, and have one or more risk factors for prediabetes or type 2 diabetes:
- If your result is normal but you’re over 45, have risk factors, or have ever had gestational diabetes, repeat the A1C test every 3 years.
- If your result shows you have prediabetes,. It is recommended to repeat the A1C test as every 1 to 2 years.
- If you don’t have symptoms but your result shows you have prediabetes or diabetes, get a second test on a different day to confirm the result.
- If your test shows you have diabetes, check your Hba1C every 3-6 month.
Dr. B. Lal Clinical Laboratories uses ion-exchange High Performance Liquid Chromatography (HPLC) technology for HbA1c testing to provide clinicians with a well-defined HbA1c peak separation that assists in the delivery of a comprehensive patient picture. (HbA1c can also be measured by other methods like immunoassay, enzyme test, capillary electrophoresis, or boronate affinity chromatography.)
Some of the glucose in our blood spontaneously binds to haemoglobin (the protein that carries oxygen in your red blood cells). This is known as haemoglobin A1C (HbA1c). HbA1c production is linked to the amount of glucose in your blood. When diabetes is inadequately controlled, blood glucose levels rise, resulting in higher HbA1c readings. Because red blood cells life span is 3-4 months, the HbA1c level in your blood shows the average amount of glucose in your blood over the past 3 months the more glucose in the blood, the more glycated haemoglobin is produced.
The test is done in a lab,using a sample of blood from your arm. You don’t need to do anything special to prepare for your HbA1C test. No fasting is necessary for this test. However, ask your doctor if othertests will be done at the same time and if you need to prepare for them.
When your doctor suspects you may have diabetes. After diabetes has been diagnosed Dr. B. Lal Clinical Laboratories Pvt. Ltd. recommends that for all persons HbA1c is checked every 3-6 months. HbA1c levels may be checked more regularly in following:
- Diabetics who have just been diagnosed,
- In those whose blood glucose levels stay excessively high, or
- When a treatment plan is changed.
If you have diabetes, get your HbA1C checked in addition to, not instead of, regular blood sugar self-testing.
Several variables might cause your HbA1C to be falsely increased or decreased, including:
- Severe anaemia, kidney failure, or liver illness.
- A less frequent kind of haemoglobin seen in persons of African, Mediterranean, or Southeast Asian heritage, as well as those suffering from specific blood diseases (such as sickle cell anaemia or thalassemia).
- Certain drugs, such as opioids and certain HIV treatments.
- Blood transfusions or loss of blood
- Pregnancy, either early or late.
Inform your doctor if any of these characteristics apply to you, and ask whether more tests are required to determine this.
