Many people wonder, “Why is Vitamin D Test necessary?” Several reasons include pregnancy, lactation, obesity, and certain medications. This article will explore some of the reasons for testing. Also, read about the various benefits of Vitamin D. Here are four other reasons why Vitamin D testing may be necessary:
Pregnancy
A Vitamin D test during pregnancy can be a great way to monitor the levels of this vitamin in your body. Studies have shown that high vitamin D levels during pregnancy are associated with low birth weight and lower bone mass in the offspring at age 20. In a recent study, Aghajafari F et al. studied the associations between maternal serum 25-hydroxyvitamin D and birth weight and the risk for type 1 diabetes in their offspring.
In a landmark study, researchers from the Medical University of South Carolina (MUSC) in Columbia, South Carolina, conducted a vitamin D test during pregnancy on 1,387 women. The researchers found that over 20 ng/ml of vitamin D levels lowered the risk of preterm birth by half. They also found that the reduction in preterm births correlated with higher levels of vitamin D. This means that even if you do not want to use a supplement to increase your vitamin D levels during pregnancy, a vitamin D test is a great way to check your levels and find out if you’re at risk for preterm birth.

Lactation
During lactation, vitamin D levels in the blood decrease slightly, but not as much as during pregnancy. This decline in 25(OH)D concentration may be due to a decrease in the availability of vitamin D in the mother’s breast milk. Furthermore, mothers with long periods of breastfeeding have higher 25(OH)D concentrations than those with short periods of lactation. This paradox might be related to the fact that breast milk converts vitamin D into the metabolite cholecalciferol.
The study population comprised 45 women (21 pregnant, 21 lactating, and 15 NPNL) from five clinics across the United States. The women were categorized according to their age, pregnancy stage, and gestational age. The pregnancy group was evaluated by ultrasound. In addition, women had to present with a singleton fetus between 20 and 30 weeks gestational age (GA), and they had to be breastfed exclusively for three months.
Obesity
The association between obesity and low vitamin D levels is well-known. However, the role of weight in determining vitamin D levels remains a topic of debate. Researchers have hypothesized that obesity may predispose individuals to fat accumulation. To address this, scientists have examined the type and location of body fat to pinpoint its relationship to obesity. They analyzed data from the Netherlands Epidemiology of Obesity Study, which included thousands of individuals aged 45 to 65. The researchers focused on total fat content, abdominal subcutaneous adipose tissue, visceral fat, and hepatic fat, and they adjusted for alcohol intake, smoking, education level, and chronic disease.
In addition to being a potential risk factor for obesity, lack of vitamin D is also associated with various other conditions. For example, older adults, those with a dark complexion, and breastfed infants may all be at risk for low vitamin D levels. Therefore, if a vitamin D test is performed, a doctor may recommend appropriate dietary and lifestyle changes based on the results. However, vitamin D supplementation should not be considered a stand-alone strategy.
Certain medication regimens
Some medications, such as birth control pills, may require Vitamin D tests. Vitamin D is necessary for the immune system. It controls inflammation and the immune response to germs and viruses. Aetna considers vitamin D testing to be exploratory and experimental. If you are unsure if your vitamin D level is average, talk to your healthcare provider to get an accurate test.
A 25-hydroxy vitamin D blood test is performed to check your vitamin D level. This simple test requires a blood sample from an arm vein or a finger prick. The results can be interpreted based on age and sex and may vary from lab to lab. A doctor may also recommend a special scan to evaluate your bone density. Although there is little evidence to support the link between vitamin D and certain diseases, vitamin D deficiency is likely to increase the risk of developing those diseases.
Skin production of vitamin D
The primary source of vitamin D is skin production, yet many people have low levels. People with darker skin often have lower blood levels of this vital vitamin. This is because the dark skin pigment, which protects us from sunlight’s damaging effects, prevents the body from synthesizing enough vitamin D. Even though we need vitamin D, too much sun exposure can cause damage to our skin and, in some cases, even cancer.
Generally speaking, skin-generated vitamin D is known as cholecalciferol or ergocalciferol. These substances enter the bloodstream after being synthesized in the epidermis after exposure to UVB rays. After synthesis, cholecalciferol and ergocalciferol are transported to the liver, where they are converted into active vitamin D, 25-hydroxyvitamin D.
Cost of a vitamin D test
If you want to know how much a vitamin D test will cost, you’ll need to know the details. The American Association for Clinical Chemistry website has the most complete and detailed information about lab tests, including vitamin D. You’ll also find answers to frequently asked questions.
The costs of a vitamin D test can be surprisingly affordable. While the test may require an office visit, blood samples are typically taken and analyzed in a medical laboratory. While vitamin D test costs are usually covered by insurance, you may need to pay a copay or deductible. As vitamin D tests are performed in a medical setting, they generally involve a blood sample drawn from the arm and analyzed in a laboratory.
