[Parameters of blood coagulation in workers of Astrakhan gas processing plant].

The workers demonstrated longer prothrombin and thrombin time showing activity of extrinsic coagulation mechanism, shorter activated partial thromboplastin time characterizing activity of intrinsic coagulation mechanism. There was no definite dependence of hemostasis parameters on age and length of service. Coagulation parameters with biochemical and hematologic studies could be used to detect hazardous influence of occupational factors on workers.
