Plasma leucine

There are 21 kinds of amino acids that make up human proteins. The plasma amino acid concentration of normal people fluctuates day and night, generally peaking between 8 and 10 in the morning and trough at midnight. The determination of amino acids and their products is of great significance for the diagnosis of congenital or acquired metabolic diseases. Clinical determination of serum or plasma leucine, to avoid the effects of food digestion and absorption, should be taken in the early morning on an empty stomach. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Lowering can be seen in infant diarrhea. Normal value: Plasma leucine: 75-175 μmol/L Above normal: Elevation is seen in hyperleucine, gout, maple syrup, and diabetes. negative: Positive: Tips: The plasma amino acid concentration of normal people fluctuates day and night, with a peak at 8-10 in the morning and a trough at midnight. When taking blood, it is necessary to avoid the effects of digestion and absorption of food. It is better to take blood on an empty stomach in the morning. Normal value 75 to 175 μmol/L. Clinical significance 1, elevated in hyperleusemia, gout, maple syrup, diabetes. 2, reduced in the baby's diarrhea. High results may be diseases: gout, diabetes considerations 1.

When taking blood, it is necessary to avoid the effects of digestion and absorption of food. It is better to take blood on an empty stomach in the morning. 2. If the specimen is not suitable for hemolysis, it may lead to a false increase in the measurement results. Inspection process Immediately after venous blood collection, the test method is the same as the fluorescence method. Not suitable for the crowd Special diseases: Patients with hematopoietic dysfunction, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye.
