What Is a Chromium Blood Test?
A chromium blood test, also known as a chromium serum test, measures the amount of chromium in the blood. The test can help diagnose chromium deficiency or chromium overdose. Chromium is an essential trace mineral for human health.
Why Get Tested?
Your healthcare provider might order a chromium blood test if they suspect you may have a chromium deficiency or overdose. Chromium deficiencies have been reported in people with diabetes, alcoholism, and HIV/AIDS. Chromium can also be found in some dietary supplements, so your healthcare provider might suggest this test if you're taking a supplement and they want to check your levels.
Preparation
No special preparation is usually necessary. Your healthcare provider might give you instructions on how to prepare for the test.
Procedure
A chromium blood test is a simple blood draw. A healthcare professional will draw a blood sample using a needle and a syringe. This procedure may be done in a healthcare provider's office or in a hospital or laboratory.
Risks
There are minimal risks associated with a chromium blood test. You may experience minor discomfort or bleeding at the needle site. Tell your healthcare provider if you're feeling lightheaded or dizzy during or after the procedure.
Types
The type of test depends on the type of chromium being measured. Chromium tests can include:
- Total chromium: A test to measure the amount of total chromium in the blood.
- Organic chromium: A test to measure the amount of chromium bound to proteins in the blood.
- Inorganic chromium: A test to measure the amount of chromium not bound to proteins in the blood.
Why Get Tested?
Chromium helps insulin to move glucose (blood sugar) from the blood into the cells where it can be used as energy. A chromium deficiency can affect the way the body processes sugar, fat, and protein. Chromium levels that are too low can lead to high blood sugar, weight gain, fatigue, and certain deficiency diseases. Chromium levels that are too high can put you at risk for certain health problems, such as liver and kidney damage.
