A vitamin D test tells you if you are getting enough vitamin D, which is important for your body. Vitamin D is examined to detect any vitamin D deficiency or overdose. Sunlight affects the body’s vitamin D levels, which is why the levels are highest in late summer and lowest in mid-winter. The vitamin D test is done on a blood sample. The test does not require fasting or sampling in the morning.
