25-OH-Vitamin-D3
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.

Vitamin B12
Vitamin B12 is an essential vitamin needed for the formation of red blood cells, the functioning of the nervous system, and the production of DNA. It is found almost exclusively in animal foods such as meat, fish, eggs, and dairy products.
A deficiency in Vitamin B12 can lead to anemia, fatigue, concentration problems, and nerve damage. Those at increased risk for a deficiency include older adults, vegetarians, vegans, or individuals with absorption disorders in the intestines.

Bilirubin, total
Bilirubin is produced during the breakdown of the red blood pigment hemoglobin and is further processed in the liver. It reaches the intestine via the bile and is eventually excreted. The total bilirubin level in the blood indicates how well this breakdown and excretion process is functioning.
Slightly elevated levels can be harmless, such as in the case of Gilbert's syndrome. However, significantly elevated levels can indicate liver or bile duct diseases and often lead to a yellowing of the skin and eyes (jaundice).

C-reactive protein (CRP)
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.

Cystatin C
Cystatin C is a protein that is produced in all body cells and filtered from the blood by the kidneys. Since the production of Cystatin C in the body is relatively constant, the value is well-suited for assessing kidney function.
In contrast to creatinine, Cystatin C increases early when kidney performance declines. Therefore, it is considered a sensitive marker for detecting early kidney weakness in a timely manner.
