The elemental composition of standard healthy adults is 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium, 1% phosphorus, 0.35% potassium, 0.25% sulfur, 0.15% sodium chloride 0.15%, magnesium 0.05%. Etc. These constant elements account for about 99.9% of body weight. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: Before the check, the taboo is not normal, the diet is not normal, and the mood is excessively tight. Normal value The elemental composition of standard healthy adults is 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium, 1% phosphorus, 0.35% potassium, 0.25% sulfur, 0.15% sodium chloride 0.15%, magnesium 0.05%. Wait. Clinical significance Abnormal results The constant elements play an important role in constituting the body tissue components and maintaining the body's internal environment. Abnormal results include acid-base imbalance, abnormal osmotic pressure, nerve and muscle excitability, and abnormal cell membrane permeability. People who need to be examined for a large amount of elements or lack of people. Precautions Inappropriate crowd: None. Taboo before the examination: the rest is not normal, the diet is not normal, and the mood is excessively tight. Requirements for inspection: Actively cooperate with the doctor's work. Inspection process Taking a sample of the body, after a certain treatment, the ratio of the major elements in the sample is measured by a reagent or an instrument, thereby obtaining the content of the constant element of the human body. Not suitable for the crowd Those without examination indications should not be tested. Adverse reactions and risks No complications.
