Overview Risks Results

Beta-carotene

The normal range is 60 to 200 mcg/dl (micrograms per deciliter).

Abnormal results will show lower-than-normal or elevated levels.

Lower-than-normal levels may indicate a diet inadequate in beta-carotene or a problem with intestinal absorption of fat-soluble substances (termed steatorrhea).

Elevated levels may indicate hypervitaminosis A (excessive Vitamin A causing headaches, yellow skin, loss of appetite, nausea, diarrhea, dry and itchy skin, hair loss, bone pain, and cessation of menstruation in women). During pregnancy, an excess of Vitamin A can cause birth defects.
