Postprandial serum zinc concentration response test (PICR)

The postprandial serum zinc concentration response test (PICR) is given to a standard diet (20% of total calories, 10% to 15% protein, 30% to 35% fat, 50% to 60% carbohydrate). Fasting (A0) and 2 hours postprandial serum zinc concentration (A2). Zinc deficiency after growth and development can hinder the growth hormone axis function and the maturation of the gonadal axis, which is characterized by growth retardation, short stature, delayed sexual development and hypogonadism. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: You should have an empty stomach before the test. Normal value The normal minimum serum zinc concentration was 47umol/L (75mg/dl). Clinical significance Abnormal results If the PICR is >15%, it indicates zinc deficiency. Digestive dysfunction and zinc deficiency affect the taste bud cell renewal and salivary phosphatase activity, resulting in hyperplasia and parakeratosis of the tongue mucosa, resulting in decreased taste sensitivity, loss of appetite, anorexia and heterophilia. Zinc deficiency after growth and development can hinder the growth hormone axis function and the maturation of the gonadal axis, which is characterized by growth retardation, short stature, delayed sexual development and hypogonadism. Immunization to reduce zinc deficiency can lead to functional damage to T lymphocytes, which is prone to infection. Precautions Inappropriate crowd: None. Taboo before inspection: should be fasting. Requirements for inspection: Serve a standard diet. Inspection process The fasting serum zinc concentration test was performed first, and the postprandial serum zinc concentration reaction test (PICR) was administered, and a standard diet was administered to measure the serum zinc concentration. Not suitable for the crowd No taboos. Adverse reactions and risks 1. Infection: Pay attention to aseptic operation when collecting blood, avoid contamination of water and other parts at the blood collection site to avoid local infection. 2, bleeding: after the blood is given a full compression time, especially coagulopathy, bleeding tendency, to avoid local subcutaneous oozing, bruising and swelling.
