Special Coagulation

The Special Coagulation department at Northern Light Laboratory serves the needs of clients throughout Eastern, Central and Northern Maine, as well as clients in Southern Maine and Vermont. A core group of specially trained technologists have completed a thorough training program prior to performing specialty coagulation testing.

Special Coagulation testing takes an in-depth look at patient’s coagulation system, investigating the causes of hemorrhage or thrombosis beyond the screening process. Accurate testing is accomplished through the use of several unique pieces of equipment, including the ACL TOP 550 by Instrumentation Laboratories. It is a fully-automated system for processing plasma samples using chromogenic, turbidometric and clotting assay methodology. The PAP-8E by Bio/Data is used to evaluate platelet function.

Northern Light Laboratory's Special Coagulation department also works with ARUP Laboratory in Salt Lake City and the Blood Center of Wisconsin to provide exceptional service in processing testing that cannot be performed in our Bangor laboratory. These referrals are processed 5 days per week and in most cases the results are made available the same week.

  • Dilute Russell’s Viper Venom Time (dRVVT)
