Blood Test for Vitamins
Blood testing for vitamin content in your body measures a whole range of vitamins, minerals, and other substances from a small sample of your blood.
Accuracy? The test is accurate in identifying the vitamins and minerals in the sample. But, the "ideal" levels are not really known. Scientists know what levels our bodies need to avoid deficiency illnesses. But researchers are still playing the guessing game when it comes to how much of each vitamin you need to protect yourself against heart disease and cancer. Keep in mind that vitamins and minerals in the bloodstream do not necessarily reflect the levels in other tissues of the body. Plus, the test may measure what is there at the time the blood is drawn. The levels can vary from day to day.
Bottom line: Skip the test and save your money. Eating a well-balanced diet - including foods from all the food groups every day - and taking a multivitamin is sufficient.
