They provide an overall picture of your body's chemical balance and metabolism. Metabolism refers to all the physical and chemical processes in the body that use energy. How the Test is Performed A blood sample is needed. Blood sampleVenipuncture is the collection of blood from a vein. It is most often done for laboratory testing.ImageRead Article Now Book Mark Article How to Prepare for the Test You should not eat or drink for 8 hours before the test. How the Test will Feel When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away. Why the Test is Performed This test gives your health care provider information about:How your kidneys and liver are working Blood sugar and calcium levels Sodium, potassium, and chloride levels (called electrolytes) ElectrolytesElectrolytes are minerals in your blood and other body fluids that carry an electric charge.

Some labs use different measurements or may test different specimens. Talk to your provider about the meaning of your specific test results. What Abnormal Results Mean Abnormal results can be due to a variety of different medical conditions. These may include kidney disease, liver disease, breathing problems, and diabetes or diabetes complications. Risks There is little risk involved with having your blood taken. Veins and arteries vary in size from one person to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleeding Fainting or feeling lightheaded Multiple punctures to locate veins Hematoma (blood accumulating under the skin) Infection (a slight risk any time the skin is broken)Open ReferencesReferencesMcPherson RA, Pincus MR.
