Lactic Acid Test

A lactic acid test is a laboratory procedure that measures the amount of lactic acid in a person’s blood. Lactic acid is a natural substance produced by the body when it breaks down carbohydrates for energy. This test can help doctors diagnose certain health conditions, such as anemia or kidney problems.

Preparation for the Lactic Acid Test

The lactic acid test only requires a small sample of blood, usually taken from a vein in the arm. This can typically be done in a doctor’s office or hospital setting. The procedure does not usually require any special preparation.

Procedure for the Lactic Acid Test

Your doctor will ask you to lie down or sit in a comfortable position.
A healthcare provider will clean and wrap an elastic band around your upper arm to make the vein swell with blood.
A small needle will be inserted into the vein and a tiny amount of blood will be collected.
The needle will be removed and a cotton or gauze pad applied to the area.
Your healthcare provider may put a bandage on the area.
The blood will be placed in a labeled tube and sent to a laboratory for testing.

Types of Lactic Acid Tests

There are two types of lactic acid tests – plasma and serum. Plasma lactic acid testing measures the lactic acid in the blood plasma, while serum lactic acid testing measures the lactic acid in the serum portion of the blood. The two tests provide the same information and can be ordered separately or together.

Risks of the Lactic Acid Test

There are no major risks associated with a lactic acid test. Some people may experience slight discomfort at the puncture site where the needle was inserted. This can easily be alleviated with a simple over-the-counter pain medication.

Why is a Lactic Acid Test Done?

A lactic acid test is usually done to check for health problems related to poor metabolism, such as kidney or liver problems. It is also used to diagnose lactic acidosis, a condition that occurs when lactic acid builds up in the body.

When is a Lactic Acid Test Done?

A lactic acid test is usually done when a person has symptoms that may be related to lactic acidosis, such as confusion, difficulty breathing, weakness, and chest pain. It may also be done if a person has an underlying medical condition that increases the risk for lactic acidosis, such as diabetes or heart failure.
