Salivary potassium

Saliva is a fluid secreted by many oral glands. The composition of saliva is very complicated, and some are closely related to plasma such as uric acid, urea, etc., but some components are not affected by plasma concentrations such as protein, electrolyte potassium and the like. Basic Information Specialist classification: oral examination classification: body fluid examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Rare. Normal value: Potassium saliva (unstimulated): 19-23mmol/L Potassium saliva (after stimulation): 18-19mmol/L Above normal: Found in cystic fibrosis, primary aldosteronism, digitalis poisoning. negative: Positive: Tips: Specimens should be sent immediately after collection. Normal value Not stimulated 19 ~ 23mmol / L. 18-19 mmol/L after stimulation. Clinical significance Elevation: seen in cystic fibrosis, primary aldosteronism, digitalis poisoning. High results may be diseases: primary aldosteronism, pediatric digitalis poisoning precautions Specimens should be sent immediately after collection. After standing at room temperature, the pH rises, the bacteria multiply, precipitates and precipitates, and the chemical composition changes, thereby affecting the detection results. Inspection process Detection operation: Potassium emits a certain wavelength of light under the excitation of flame. The wavelengths of potassium emission are 765 nm and 589 nm, respectively, and the light intensity is proportional to its concentration within a certain range. Potassium saliva and standard solution were diluted 100 times with distilled water. Zero the distilled water and measure the light intensity of the standard solution and salivary potassium. Not suitable for the crowd Those who do not have an indication for examination should not be tested. Adverse reactions and risks no.
