Beta-carotene blood test

What is a Beta-Carotene Blood Test?

A Beta-carotene blood test is used to measure the amount of beta-carotene present in the blood. Beta-carotene is a powerful antioxidant that is found in many plant-based foods, and is converted to vitamin A in the body. The test helps to evaluate a person’s dietary and lifestyle habits, risk of certain vitamin deficiencies, as well as potential health concerns related to beta-carotene levels.

Preparation

No special preparations are needed for this test. However, it is recommended to avoid consuming carotene-rich foods such as carrots, sweet potatoes, spinach, and pumpkins for 24 hours prior to the test. The doctor may also ask the patient to fast for 8-12 hours prior to the test.

Procedure

The Beta-carotene blood test is performed by drawing blood from a vein in the arm. After the needle is inserted, a small amount of blood will be collected in a vial or syringe. Pressure is then applied to the puncture site to stop any bleeding. The sample is then sent to the lab for analysis.

Types of Beta-carotene Test

There are two types of Beta-carotene test: serum beta-carotene test and plasma beta-carotene test. The serum test measure the amount of beta-carotene that is present in the serum of the blood, while the plasma test measure the amount of beta-carotene in the plasma portion of the blood.

Risks

The Beta-carotene blood test is generally safe and carries no risk. However, as with any blood test, there is a small risk of infection or bruising at the puncture site.

Why it is Done
