Why Is Fasting Required Before Blood Tests
Fasting before a blood test helps improve the accuracy and reliability of the test. Accurate test results are a critical component of diagnosing various health conditions and monitoring the effectiveness of treatment plans.
Your diet contains a range of nutrients, including carbohydrates, proteins, fats, minerals and vitamins. When you eat and drink normally, those nutrients are broken down and absorbed into your bloodstream. This can impact the levels of those substances in the blood and skew lab test results.
For example, certain methods of diabetes testing measure the patients baseline blood sugar levels after a period of fasting. Eating directly before the test will cause the patients blood sugar to spike, leading to an inaccurate test result. The patient could be misdiagnosed with prediabetes or diabetes, unless their doctor recommends that they complete a second test.

What Is Hyperglycemia
Hyperglycemia is a fancy way to say âhigh blood sugarâ. People without diabetes usually maintain a fasting blood sugar of less than 100 mg/dl. The goal for managing diabetes is to achieve glucose values as close to this as possible, but the recommended range is 80-130 mg/dl.
There is no specific value used to define hyperglycemia in all individuals. In general, a glucose level above 160-180 mg/dl is considered hyperglycemia. The best way to define it, though, is by talking with your medical team. Hyperglycemia is really defined as any blood sugar that is above the upper limit of your individualized range.
- Fasting hyperglycemia is a blood sugar that is higher than the desirable level after 8 hours without food or drink.
- Postprandial hyperglycemia is when the blood sugar is higher than 180 mg/dl 1-2 hours after eating a meal.
Both types of hyperglycemia may indicate the need to adjust your treatment plan. If you notice high blood sugars at the same time of day for 3 days in a row, this I considered a âpatternâ. If you recognize a pattern, contact your doctor or dietitian for suggestions. Tracking your blood sugar allows early recognition of possible patterns and is an important way to self-manage and start problem solving.

Why Doctors Order It
A fasting blood glucose test is done to screen for prediabetes and diabetes. It also helps doctors monitor diabetes and determine if medications and dietary changes are having an effect .
Your fasting blood glucose level is the lowest your blood sugar can be because the influence of recent meals is minimized .
Fasting blood sugar is often checked alongside HbA1c , which is a measure of your blood sugar levels over the past three months. The more sugar there is in the blood, the more it will attach to hemoglobin, raising HbA1c .
Taken together, the two offer more information than each test alone. For example, even if your blood sugar levels are very high at one random point, they may have been mostly low over the past couple of months . On the other hand, HBA1c could be higher but your glucose levels at the moment lower.
Apart from diabetes, abnormal levels can point out issues such as insulin resistance, hormonal imbalances, and pancreatic, liver, or kidney disease.
Signs That Blood Sugar Levels Are High
People with high blood sugar may:
- pee a lot. When blood sugar levels get too high, the kidneys flush out the extra glucose into your urine , which is why people who have high blood sugar levels need to pee more often and in larger amounts.
- drink a lot. Because you’re losing so much fluid from peeing so much, you can get very thirsty.
- lose weight. If there isn’t enough insulin to help the body use glucose, the body starts to break down your muscle and fat for energy and you lose weight.
- feel tired. Because the body can’t use glucose for energy properly, you may feel really tired.
High blood sugar levels don’t always cause these symptoms. Sometimes you can have high blood sugar levels without even knowing it. But if left untreated, they can cause serious health problems. That’s why it’s important to work with your parents and diabetes team to keep your blood sugar levels in a healthy range. This can mean checking your blood sugar levels a few times a day, even when you feel fine.
