25-OH vitamin D is the storage form of vitamin D that the body produces in the liver from vitamin D formed with 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.

Cortisol is a hormone produced in the adrenal cortex that controls metabolism and the body's stress response. It regulates blood sugar levels, blood pressure, and influences the immune system. Cortisol typically follows a daily rhythm, with the highest levels in the morning and the lowest at night.

Permanently elevated cortisol levels can lead to weight gain, high blood pressure, sleep disturbances, and a weakened immune system. Too low levels indicate adrenal insufficiency and can be associated with fatigue, low blood pressure, and weakness.

CRP (C-reactive protein) is a protein that the liver produces in response to inflammation. The level in the blood rises quickly when infections, tissue damage, or other inflammatory processes occur in the body. Therefore, CRP is often used as a general marker of inflammation.

A significantly elevated CRP level usually indicates an acute infection, while slightly elevated levels can also occur in chronic diseases. Normal values generally rule out a relevant inflammation.

Ferritin is a protein that stores iron in the body and releases it when needed. The ferritin level in the blood indicates how well the body's iron stores are filled and is therefore often used to assess iron status.

Low values usually indicate an iron deficiency or anemia. Elevated values may suggest inflammation, liver diseases, or iron overload.

TSH (Thyroid-stimulating hormone) is produced in the pituitary gland and controls the activity of the thyroid gland. It stimulates the thyroid to produce the hormones T3 and T4, which influence metabolism and many body functions.

High TSH levels usually indicate an underactive thyroid, as the body tries to boost hormone production. Low TSH levels, on the other hand, suggest an overactive thyroid.
