Can You Drink Alcohol If Youre Fasting Before A Blood Test
Some blood tests, such as those that assess liver health or triglyceride levels, may require you to not drink any alcohol for a full 24 hours.

Which Tests Help My Health Care Professional Know What Kind Of Diabetes I Have
Even though the tests described here can confirm that you have diabetes, they cant identify what type you have. Sometimes health care professionals are unsure if diabetes is type 1 or type 2. A rare type of diabetes that can occur in babies, called monogenic diabetes, can also be mistaken for type 1 diabetes. Treatment depends on the type of diabetes, so knowing which type you have is important.
To find out if your diabetes is type 1, your health care professional may look for certain autoantibodies. Autoantibodies are antibodies that mistakenly attack your healthy tissues and cells. The presence of one or more of several types of autoantibodies specific to diabetes is common in type 1 diabetes, but not in type 2 or monogenic diabetes. A health care professional will have to draw your blood for this test.
If you had diabetes while you were pregnant, you should get tested no later than 12 weeks after your baby is born to see if you have type 2 diabetes.

Fasting Blood Glucose Level
A glucose level below 11.1 mmol/L on a random blood sample does not rule out diabetes. A blood test taken in the morning before you eat anything is a more accurate test. Do not eat or drink anything except water for 8-10 hours before a fasting blood glucose test. A level of 7.0 mmol/L or more indicates that you have diabetes.
If you have no symptoms of diabetes but the blood test shows a glucose level of 7.0 mmol/L or more, the blood test must be repeated to confirm you have diabetes. If you do have symptoms and the blood test shows a glucose level of 7.0 mmol/L or more, the test does not need to be repeated. See the separate leaflets called Type 1 Diabetes and Type 2 Diabetes for more details.
When Will I Get The Test Results
Most fasting lab results are available for your doctor in about 24 hours. However, some tests may take longer to complete. The lab will provide a report to your doctor, and your doctor will use the report to help with next steps in your diagnosis and treatment.

What Is A Lipid Panel Used For
Healthcare providers use lipid panels to help assess someones cardiovascular health by analyzing cholesterol in their blood and to help diagnose other health conditions.
Reasons a provider may order a lipid panel include:
- As a routine test to determine if your cholesterol level is normal or falls into a borderline-, intermediate- or high-risk category.
- To monitor your cholesterol level if you had abnormal results on a previous test or if you have other risk factors for heart disease.
- To monitor your bodys response to treatment, such as cholesterol medications or lifestyle changes.
- To help diagnose other medical conditions, such as liver disease.
Who Orders My Blood Tests
Your doctor typically orders blood tests for you during a physical, checkup, or an appointment intended for a specific condition.
Blood testing is usually partially or fully covered by insurance. Ordering tests through your medical provider ensures that youre not paying too much. Your doctor can also advise you on how to choose testing facilities that are reliable, well-managed, or convenient for you.
Its possible to order your own blood tests without a doctor or even health insurance, but its not recommended. You may end up paying the full cost by not going through an insurance plan, which can be expensive.
And some blood testing facilities may not give you accurate results. One infamous case of this is Theranos, a Palo Alto, California, biotechnology firm shut down in 2018 when an investigation uncovered lies and fraud around the accuracy of its private blood testing technology.
Normal levels can also vary by age.

Do I Need To Fast For A Lipid Panel
In most cases, you need to fast for 10 to12 hours before your lipid panel blood test. Fasting means not eating or drinking anything except water. In some cases, getting a lipid panel test without fasting is possible.
In any case, its important to ask your healthcare provider in advance about whether you need to fast before the test. Always follow the instructions that your provider gives you. If your provider has instructed you to fast and you accidentally break the fast , please let your provider know because the test is not as useful without fasting.
How It Is Done
The health professional taking a sample of your blood will:
- Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
- Clean the needle site with alcohol.
- Put the needle into the vein. More than one needle stick may be needed.
- Attach a tube to the needle to fill it with blood.
- Remove the band from your arm when enough blood is collected.
- Apply a gauze pad or cotton ball over the needle site as the needle is removed.
- Apply pressure to the site and then a bandage.
