"Is there an accurate blood test after eating?" This is a question many people ask. Depending on the type of disease and the specificity of each type of test, the absorption of food will affect the results of blood tests. The following article will tell you the types of blood tests that do and do not require fasting.
Types of blood tests that require fasting
1.1. Diabetes test
1.2 Blood fat test (related to heart problems)
Indicators include total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides.
If the levels of LDL-cholesterol and triglycerides are high, the patient will be at high risk of cardiovascular problems. Blood lipid testing is usually recommended for people over 45 years old every 5 years or patients with existing hypertension and diabetes. If the patient already has cardiovascular disease, the doctor will order this test regularly to measure and control the amount of blood fat in the body. Like the blood sugar test, this test also requires an 8- to 10-hour fast because food will affect the results.
Eating or drinking alcohol before a blood test is not advisable because it will affect the results of the blood fat test.
1.3 Tests to assess liver function
