Introduction
Generally speaking, there is no such thing as a "five-item test for fat-soluble vitamins." Tests for fat-soluble vitamins include vitamin A, vitamin D, vitamin E, vitamin K1, and vitamin K2. Doctors may need to measure vitamin A and vitamin A esters in plasma. If any symptoms or discomfort occur, it is recommended to seek medical attention promptly.
Generally speaking, there is no such thing as a "five-item test for fat-soluble vitamins." Tests for fat-soluble vitamins include vitamin A, vitamin D, vitamin E, vitamin K1, and vitamin K2. Specific analyses are as follows:
1. Vitamin A
Doctors need to measure the levels of vitamin A and vitamin A esters in plasma. If a patient's plasma shows significantly elevated levels of vitamin A and increased vitamin A esters, vitamin A excess can be preliminarily diagnosed.
2. Vitamin D
This test assesses the level of vitamin D in the body to determine whether vitamin D deficiency exists. If a patient's vitamin D level is below the normal range, it may indicate vitamin D deficiency.
3. Vitamin E
A venous blood sample is taken for testing. By measuring the concentration of vitamin E in the blood, the presence of vitamin E deficiency can be determined.
4. Vitamin K1
Vitamin K1 deficiency can be assessed by measuring prothrombin levels in the blood. If prothrombin levels fall below 50% of normal, vitamin K1 deficiency is generally suspected.
5. Vitamin K2
Symptoms such as nosebleeds, gum bleeding, or subcutaneous bleeding may be caused by vitamin K2 deficiency.
If any discomfort or symptoms occur, it is recommended to seek medical attention promptly and receive symptomatic treatment based on a doctor’s diagnosis.
