Nutritional deficiency occurs when the body is deprived of vital nutrients. While macros like carbohydrates, proteins, and fats are essential for the body, do not ignore micronutrients. These include vitamins and minerals. They help the body fight against infections. A nutritional deficiency can result in several health ailments.  As such, getting a regular vitamin deficiency test or a combined vitamin and mineral deficiency test is crucial.
Generally, the level needed depends on your age. The most common nutritional deficiencies affecting the body include iron deficiency, deficiency of vitamin A, B1, B3, B9, and B12. Read on for a better idea of these tests and to understand the associated deficiencies.
Vitamin D is vital for bone and muscle health. It supports your immune system. About 1 billion people around the world do not get the required vitamins D.  Vitamin D deficiency has symptoms like muscle pain, anxiousness, tiredness, or weak bones. The best source of vitamin D is sunlight.
Vitamin D levels can be best measured with a 25-hydroxy vitamin D test. A range between 50-175 nmol/L is normal. A range between 75-100 nmol/L is optimal. Some foods to gain vitamin D include fatty fish, mushrooms, and egg yolks.

An active B12 blood test measures the amount of vitamin B12 available in your body for use. You can also opt for a total B12 test. An active B12 range between 37.5-188 pmol/L is normal. The normal range for the total B12 test is between 300- 569 pmol/L.
Iron deficiency is the most widespread nutritional deficiency in the world. It can lead to anemia. More than 30% of the world’s population is anemic.  Iron deficiency is mostly found among pregnant women, infants, cancer patients, blood donors, or those with heart failure.

There are several tests including a blood test to check iron deficiency. Your hemoglobin, serum ferritin levels are also checked. The normal range for serum ferritin is 13-150 ng/I for women and 30-400 ng/I for men. The hemoglobin should be 120-160 g/L for women and 130-170 g/L for men. Further, the total iron-binding capacity (TIBC) should be 45-72 umol/L for both men and women.
Vitamin C plays a major role in the growth and repair of body tissues. Weakness, muscular pain, sunken eyes, and loss of appetite are some of the symptoms of vitamin C deficiency. Other symptoms include rough and bumpy skin, dry and damaged skin, easy bruising, slow healing of wounds, swollen joints, tooth loss, fatigue, stress, and low immunity.

A vitamin C blood test checks vitamin C deficiency. A capillary fragility test is also done to determine the same using a blood pressure cuff. You can consume vitamin C tablets or eat vitamin C-rich foods to prevent the deficiency. Citrus, red and green peppers, tomatoes, broccoli, and greens are some good sources of vitamin C.

A mineral panel test identifies deficiencies by testing the blood for key minerals. The test involves minerals like calcium, iodine, magnesium, zinc, iron, and copper. The level of sodium, chloride, potassium, and bicarbonate are tested by an electrolyte panel. Electrolytes are minerals that hydrate the body, rebuild damaged tissues and help in muscle function.
A vitamin profile test, which checks Vitamin B12, Vitamin D, and folic acid is a good first step to identify nutritional deficiencies and take necessary precautions. Taking vitamin and mineral supplements can help boost the immune system, but only if done in the right way. Ideally, it is always better to consume vitamin and mineral-rich foods to combat any nutritional deficiency.
