Blood Glucose Levels Move Up And Down
Your results can vary because of natural changes in your blood glucose level. For example, your blood glucose level moves up and down when you eat or exercise. Sickness and stress also can affect your blood glucose test results. A1C tests are less likely to be affected by short-term changes than FPG or OGTT tests.
The following chart shows how multiple blood glucose measurements over 4 days compare with an A1C measurement.
Blood Glucose Measurements Compared with A1C Measurements over 4 Days
The straight black line shows an A1C measurement of 7.0 percent. The blue line shows an example of how blood glucose test results might look from self-monitoring four times a day over a 4-day period.
Random Plasma Glucose Test
A random blood glucose test is a blood test thats performed any time of day that you arent fasting. It measures the sugar level in your blood at that moment in time.
An RPG result thats over 200 mg/dL is indicative of diabetes, especially if youre having symptoms of diabetes such as excessive thirst, hunger, or urination.
If your level is higher, your doctor will use one of the other tests listed to confirm the diagnosis.
What Does Hba1c Mean
HbA1c is whats known as glycated haemoglobin. This is something thats made when the glucose in your body sticks to your red blood cells. Your body cant use the sugar properly, so more of it sticks to your blood cells and builds up in your blood. Red blood cells are active for around 2-3 months, which is why the reading is taken quarterly.
A high HbA1c means you have too much sugar in your blood. This means youre more likely to develop diabetes complications, like serious problems with your eyes and feet.
Knowing your HbA1c level and what you can do to lower it will help you reduce your risk of devastating complications. This means getting your HbA1c checked regularly. Its a vital check and part of your annual review. Youre entitled to get this test at least once a year. But if your HbA1c is high or needs a little more attention, itll be done every three to six months. It’s really important not to skip these tests, so if you haven’t had one in over a year contact your healthcare team.
Once you know your HbA1c level, its important that you understand what the results mean and how to stop them from getting too high. Even a slightly raised HbA1c level makes you more at risk of serious complications, so get all the facts here and be in the know about HbA1c.

How Do We Achieve Remission
Significant weight loss appears to be the most effective way to achieve type 2 diabetes remission. Professor Roy Taylor, a leading researcher of type 2 diabetes, and colleagues at Newcastle University conducted the first ever dietary and lifestyle intervention trial with remission as the primary endpoint. This was called the DiRECT study. 320 participants, all diagnosed with type 2 diabetes within the last 6 years, were randomised into either the intervention group or the control group.
The intervention was a very low-calorie diet programme. Participants dramatically reduced energy intake to 850 calories a day and then were slowly reintroduced to a regular, healthy diet to maintain weight loss. The control group received the usual current treatment on the NHS for type 2 diabetes.
This study is ongoing, but so far the results have demonstrated that after 1 year, those in the intervention group lost significantly more body weight compared to the control group . In addition, 46% of the intervention group went into remission, compared to only 4% in the control group.
At 2 years, 36% of those who began the trial in the intervention group were in remission as opposed to 3% of those in the control group.
These results suggest that significant weight loss can reverse type 2 diabetes and result in regular insulin activity for some, even if the individual has been diagnosed up to 10 years ago.
How Precise Is The A1c Test
When repeated, the A1C test result can be slightly higher or lower than the first measurement. This means, for example, an A1C reported as 6.8 percent on one test could be reported in a range from 6.4 to 7.2 percent on a repeat test from the same blood sample.3 In the past, this range was larger but new, stricter quality-control standards mean more precise A1C test results.

Who Should Get An A1c Test And When
Testing for diabetes or prediabetes:Get a baseline A1C test if youre an adult over age 45or if youre under 45, are overweight, and have one or more risk factors for prediabetes or type 2 diabetes:
- If your result is normal but youre 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, talk to your doctor about taking steps now to improve your health and lower your risk for type 2 diabetes. Repeat the A1C test as often as your doctor recommends, usually every 1 to 2 years.
- If you dont 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, ask your doctor to refer you to diabetes self-management education and support services so you can have the best start in managing your diabetes.
Managing diabetes:If you have diabetes, get an A1C test at least twice a year, more often if your medicine changes or if you have other health conditions. Talk to your doctor about how often is right for you.

Perspective On Treatment Targets
Medical treatment guidelines reflect an extensive body of research and the time-tested input from leading experts within a given field. The expectation we all have is that this process provides recommendations that are reflective of best practice for the general patient population they address. Ideally, these guidelines provide a framework for treatment, and then they are individualized to best meet the needs of the patient and their unique physiology and lifestyle. The approach to handling T2D is no different. In addition to medical intervention, how we eat, move, sleep and think all have the power to dramatically influence our health. What we know and how we approach the treatment of T2D is a dynamic and evolving process, but a thorough understanding of the treatment targets for the disease and how they influence the possible outcomes for patients must be our ultimate guide on the journey to wellness.

Oral Glucose Tolerance Test
The oral glucose tolerance test takes a little more time than the other two glucose tests for diabetes. In this test, your blood is taken after an overnight fast, and then again two hours after you drink a sugary drink.
Its normal for blood sugar to rise after the drink. Normal blood sugar falls to below 140 mg/dL within two hours, however.
If your blood sugar is between 140 and 199 mg/dL, your doctor will diagnose prediabetes. Anything 200 mg/dL or above is diagnostic for type 2 diabetes.

You should have healthy fats each day as well.
Using the information from your food log, you can begin to make small changes. The goal is to choose less processed, whole foods, instead of highly processed foods that contain added sugar, little fiber, and unhealthy fats.
For example, if you arent eating the recommended servings of vegetables, try adding one serving of vegetables a day to your diet.
You can do this by having a salad with lunch or dinner, or snacking on carrot sticks. Just be careful about add-ons such as salad dressing or dips. They can sneak in unhealthy fats or extra calories. Check out these 10 healthy salad dressing recipes.
Youll also want to work on reducing the number of empty-calorie foods and beverages youre consuming, as well as switching out simple carbohydrate foods for complex carbohydrates. Examples of substitutions you can try to include:
Type 1 And Type 2 Diabetes Treated With Insulin
For people with type 1 diabetes, monitoring BG is essential to achieving and maintaining good glycemic control. In a large cohort study, performance of 3 self-tests per day was associated with a statistically and clinically significant 1.0% absolute reduction in A1C . The evidence is less certain in people with type 2 diabetes treated with insulin, although the above principle likely applies . In a large, non-randomized study of individuals with stable type 2 diabetes using insulin, testing at least 3 times a day was associated with improved glycemic control . More frequent testing, including preprandial and 2-hour postprandial PG and occasional overnight BG measurements, is often required to provide the information needed to reduce hypoglycemia risk, including unrecognized nocturnal hypoglycemia .

Diabetes Tracking And Treatment
- Follow your diabetes treatment plan: Understand the treatment plan before leaving the healthcare providers office and discuss barriers that could prevent you from following the program. Attend all follow-up visits.
- Consistently take prescribed medications: If a healthcare provider has prescribed medications to reduce blood sugar levels, take them regularly. Some people only take medication when they arent feeling well, but these medications dont work unless taken consistently.
- Monitor and track blood sugar: Regular blood sugar monitoring is the most important step in diabetes management, according to the CDC. Healthcare providers can inform patients of different types of meters and help patients find the best one for them. Providers can also tell patients how often to check their blood sugar and what their target blood sugar range is.Keep a log of your blood sugar levels to look for patterns and triggers for blood sugar spikes and lows. If you wear a continuous glucose monitor, you can use the data. Learning what causes blood sugar to rise or decrease can help you create a plan to keep it consistent.
Type 2 Diabetes Not Treated With Insulin
For people with type 2 diabetes treated with healthy behaviour interventions, with or without noninsulin antihyperglycemic agents, the effectiveness and frequency of monitoring BG in improving glycemic control is less clear . A series of recent meta-analyses, all using different methodologies and inclusion criteria, have generally shown a small benefit to reducing A1C in those individuals performing SMBG compared to those who did not . The magnitude of the benefit is small, with absolute A1C reductions ranging from 0.2% to 0.5%. These analyses demonstrated greater A1C reductions in those performing SMBG when the baseline A1C was > 8% . SMBG has been demonstrated to be most effective in persons with type 2 diabetes within the first 6 months after diagnosis . Also of significance, there is no evidence that SMBG affects one’s satisfaction, general well-being or general health-related quality of life .

Type 2 diabetes causes the body to become resistant to the hormone insulin. This hormone unlocks cells. There are two types of diabetes: type 1 and type 2. While both types of the disease can cause problems, you can minimize the impact by following healthy eating and being physically active. The sooner you know more about diabetes, the better prepared you will be to deal with it. Once you know more about the disease, youll be better prepared for treatment.
Type 2 diabetes is a chronic condition that causes the body to produce too much insulin. It is also known as type 2 diabetes. If you have type 1, you can control your blood glucose levels by eating a balanced diet. If you have type 2 diabetes, you can even prevent it by adopting healthy lifestyle habits and modifying your diet. Its important to seek information that can help you be your own health advocate. There are many different types of diabetes, so its important to learn as much as you can about the condition.
A1c Ranges And What They Mean
An A1C result is presented as a percentage, which reflects the percentage of glucose and hemoglobin that are bound together. For example, the A1C level where there are five glycated hemoglobin out of 100 hemoglobin would be 5%.
The A1C ranges for normal, prediabetes, and diabetes are as follows:
- Normal: Less than 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
The higher the A1C, the higher your blood glucose levels have been. If your A1C falls into the range of prediabetes, you should talk to your healthcare provider to determine the best way to prevent type 2 diabetes because prediabetes is a known risk factor of type 2 diabetes. In general, within the prediabetes range, the higher the A1C, the greater the risk of diabetes.
The A1C test should not be used to diagnose type 1 diabetes, gestational diabetes, or cystic fibrosis-related diabetes.

Hba1c Levels And Targets
If you have diabetes, an ideal HbA1c level is 48mmol/mol or below.
But everyones different. So your healthcare team may give you an individual target level that takes into account your current level and when your next test is. So you can bring it down in stages and isnt a sudden big drop.
And were not saying its easy to get to and stay at this level. We know its difficult, and were here to give you advice and information to help.
Small Changes In Temperature Equipment Or Sample Handling
Even when the same blood sample is repeatedly measured in the same lab, the results may vary because of small changes in temperature, equipment, or sample handling. These factors tend to affect glucose measurementsfasting and OGTTmore than the A1C test.
Health care professionals understand these variations and repeat lab tests for confirmation. Diabetes develops over time, so even with variations in test results, health care professionals can tell when overall blood glucose levels are becoming too high.

Check Your Blood Sugar Levels As Your Doctor Has Directed
Work with your doctor to determine if, and how often, you should check your blood sugar. You may be tempted to pick up an A1C home testing kit, but Dowdell does not recommend doing that. As he mentions, day-to-day fluctuations in your blood sugar can be masked by an A1C result that is at your goal level. Instead, if you have a personal continuous glucose monitor, such as a Dexcom G6 or a Freestyle Libre , Dowdell recommends checking your time in range to see if you are at the optimal level. For many people that is 70 to 180 milligrams per decilter , according to ADA guidelines. Having your A1C checked by your healthcare provider every three to six months is sufficient, he adds.
Understanding your A1C levels is an important part of your overall diabetes management. If you have any questions about your A1C levels or what they mean, dont hesitate to ask your doctor.
