There are many reasons for high prealbumin, which are usually seen in over-nutrition, use of drugs, blood concentration and other conditions. 1. Excessive nutrition: If people use health care products or have a high protein diet, the nutrition in their body is excessive, exceeding the daily requirement, and the prealbumin will be increased. 2. Use of drugs: The use of steroidal drugs, such as glucocorticoids and androgens, can cause an increase in prealbumin in the body. It is usually seen in people who need to be treated with high doses of steroids. 3. Concentration of blood: Concentration of blood for various reasons can lead to a relative excess of prealbumin in the examination, such as prolonged fasting and water fasting, heatstroke, profuse sweating, diarrhea and other loss of body fluids. In addition, hyperadrenal secretion and severe renal failure can also lead to an increase in prealbumin. When the laboratory indicators appear obvious abnormalities, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
