cells in saliva

Saliva is the secretion of the parotid gland, submandibular gland, sublingual gland, and scattered small salivary glands. Its secretion is regulated by nerve reflexes. Saliva contains more than 99% water; solid content accounts for about 0.7%, of which organic matter accounts for about 0.5%, inorganic matter accounts for about 0.2%, in addition, a small amount of white blood cells, epithelial cells (from oral mucosa and salivary glands), trace foods And microorganisms in the mouth. Basic Information Specialist classification: oral examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: Specimens should be sent immediately after collection. Normal value There are no red blood cells in normal saliva, and a small number of squamous epithelial cells and white blood cells can be seen. The white blood cell count was 0.54 x 109 / L. Clinical significance 1. When the oropharynx and salivary gland are infected, stones or malignant tumors, the white blood cells in the saliva increase. 2. When the oropharynx or salivary gland is bleeding, red blood cells can be detected in the saliva. 3. Cytological examination with saliva sediment smears helps in the diagnosis of inflammation and tumors. Detection of cancer cells in saliva is a strong evidence for the diagnosis of oral organs and salivary gland malignancies. High results may be diseases: pediatric fungal infection stomatitis, parotid malignant tumors Specimens should be sent immediately after collection. After standing at room temperature, the pH rises, the bacteria multiply, precipitates precipitate, and the chemical composition changes. Inspection process Immediately after the specimen was collected, the test method was carried out by using a saliva-coated slide with a little saline and direct microscopic examination. Not suitable for the crowd Those without examination indications should not be tested. Adverse reactions and risks no.
