Introduction
To check for vitamin deficiency, tests such as complete blood count (CBC), blood biochemistry, and urinalysis are performed. The CBC helps detect vitamin levels. Tests for riboflavin, coagulation function, and serum retinol levels are used to assess deficiencies in vitamins A, K, and B2. Serum vitamin level measurements determine the status of vitamins A, D, and E. Vitamins B and C are water-soluble; their deficiencies are evaluated through urine tests.
Generally, vitamin deficiency can be assessed through routine blood tests, blood biochemical examinations, urine tests, and other related tests to determine the specific vitamin status in the body. The details are as follows:
1. Routine Blood Test
A routine blood test performed after drawing blood can measure the levels of vitamins in the body, helping to determine whether there is a vitamin deficiency and identify the specific type of deficiency.
2. Blood Biochemical Test
This test evaluates parameters such as riboflavin levels, coagulation function, and serum retinol levels to assess deficiencies in vitamins A, K, and B2. Measuring serum vitamin levels can also determine the body's content of vitamins A, D, E, and folate.
3. Urine Test
Vitamins B and C are water-soluble and are excreted through urine. Therefore, urine tests can help determine whether there is a deficiency in vitamin B or C.
In addition, isotope assays and other specialized tests may also be used for assessment. If vitamin deficiency is confirmed through testing, active treatment under medical supervision is necessary.
