fecal potassium

K+ is often used in the study of metabolic balance, and it is important to balance the water and electricity in the body of vitamins. It is often measured by flame photometry. Potassium (Potassium.K), a project for stool inspection. This is often used in studies of metabolic balance. Patients with severe diarrhea can reach 60mmol / 24h or more. Infants are less able to counterbalance water and electrolytes than adults. It should be noted that potassium can be excreted in large amounts from feces. After secretion of the villus tumor of the colon and rectum, the potassium in the feces can be greatly increased. Potassium is abundant in animal and plant foods. The source of potassium in human body is obtained from food. The potassium intake of healthy people is enough for physiological needs. The absorption of potassium is very complete. Only about 10mmol is excreted from the feces. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Tips: Tell the doctor about the history of medication. Normal value 5 mmol/d. Clinical significance Abnormal results: (1) severe diarrhea can reach 60mmol / d or more, primary aldosteronism, colon and rectal villus tumor secretion, the amount of potassium in the feces can be increased. (2) The ability of infants to resist imbalance water and electrolyte disturbance is not as good as that of adults. It should be noted that potassium can be discharged from feces in large quantities. Need to check the crowd: Severe diarrhea. High results may be diseases: electrolyte imbalance, primary aldosteronism considerations Note when checking: 1. Tell the doctor about the history of medication. 2. The fecal specimen should be stored at 2 to 4 °C. Not suitable for the crowd: all suitable for the crowd. Inspection process Detection by flame photometry: Flame photometry is an atomic emission spectroscopy using a flame as an excitation source. The sample is evaporated, ionized, atomized, and excited by the thermal and chemical effects of the flame (1800-2500 ° C). According to the relationship between the emission intensity I of the characteristic line and the concentration of the element in the sample, the formula I=acb (a, b is a constant), the emission intensity of the analysis line of the unknown sample to be tested and a series of The flame atomic spectrum of the element is quantitatively analyzed by comparing the measured intensity of the concentration standard sample. The device used for the measurement was a flame photometer. The method has the advantages of being simple and fast, and having a small amount of sampling. Mainly used for the determination of alkali metals and alkaline earth metals. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally not.
