[Study of salivary lactoferrin in prophylactic examinations]

Immunochemical testing of salivary samples of 73 patients revealed a positive correlation between increased level of lactoferrin and the presence of chronic pancreatoduodenal diseases (gastroduodenitis, gastroduodenal ulcers, polyps of the antral portion of the stomach, cholecystitis, cholangitis, cholelithiasis, hepatitis, and pancreatitis, correlation coefficient 0.9). The test is proposed as a cheap and informative method for screening of the above diseases.
