Vitamin D Check Plus - avi

25-OH vitamin D is the storage form of vitamin D that the body produces in the liver from vitamin D formed by sunlight or food. Vitamin D supports calcium absorption, ensures healthy bones and teeth, and plays an important role for muscles, nerves, and the immune system.

The 25-OH vitamin D test is the best method to check vitamin D status. Low levels can indicate too little sunlight, an unbalanced diet, or diseases and are associated with bone diseases such as osteoporosis or rickets. Excessive levels usually result from too high supplement doses and can strain the kidneys and liver.

Calcium is an essential mineral primarily stored in bones and teeth. It ensures the stability of the skeleton and plays an important role in muscle function, blood clotting, and nerve signal transmission. A blood test measures the portion circulating in the blood.

Too low calcium levels can cause muscle cramps, tingling, or heart rhythm disturbances. Too high levels often indicate parathyroid disorders, certain tumors, or excessive intake of vitamin D.

Albumin is the most common protein in blood plasma and is produced in the liver. It retains fluid in the vascular system and transports vitamins, enzymes, and hormones.

A deficiency may be caused by liver or kidney diseases, inflammation, or poor protein supply. High albumin levels occur with fluid loss or a very high-protein diet. Since albumin also reflects the nutritional situation, persistently low levels indicate insufficient protein intake and an increased risk of muscle weakness or infections.
