Saliva sodium/potassium ratio

There are many factors affecting the concentration of saliva electrolyte. The changes of various electrolytes in a day have certain regularity, so the time for collecting specimens should be consistent for each time, so as to make dynamic observation. Basic Information Specialist classification: oral examination classification: body fluid examination Applicable gender: whether men and women apply fasting: fasting Tips: Specimens should be sent immediately after collection. Normal value The sodium/potassium ratio of saliva is >0.5. Clinical significance Salivary sodium/potassium ratio decreased: <0.4, found in aldosteronism. Low results may be diseases: precautions for primary aldosteronism 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, which affects the detection results. Inspection process Test operation: Sodium, potassium and standard solutions of saliva were diluted 100 times with distilled water. Zero the distilled water, measure the light intensity of the standard solution and sodium and potassium of saliva, and then calculate the ratio. Not suitable for the crowd Those without indications should not be tested. Adverse reactions and risks no.
