Vitamin B6 Blood Test
Test Code: 004655
Specimen Type: Blood
Vitamin B6 Blood Level Test (Labcorp)
This test measures levels of Vitamin B6 in the blood. B6 is a nutrient in the B family of vitamins which is essential for a healthy immune system, nervous system, and metabolism. Like other B Vitamins, B6 must come from the food a person eats. Sources of Vitamin B6 include pork, fish, chicken, bananas, wheat germ and legumes. Deficiency in B6 is often accompanied by deficiencies in other B Vitamins. B Vitamin deficiency is uncommon but can occur in cases of malnutrition, chronic alcoholism or when a person has a malabsorption disorder such as Celiac Disease. Some conditions which cause chronic diarrhea, as well as some types of cancer, can result in B vitamin deficiency.
This test is typically ordered when a person has a condition which puts them at risk for vitamin deficiency or has symptoms associated with deficiency such as numbness or tingling in the extremities, skin rash, sores in or around the mouth, anemia, depression, irritability, and chronic fatigue.
