Bio-Analytical Laboratories, located in Doyline, Louisiana, approximately 30 miles east of Shreveport, is a small woman-owned business specializing in environmental biomonitoring and Toxicity Reduction Evaluations for NPDES permits, and microbiological analysis.  Established in 1993, the goal of Bio-Analytical was to offer the client a laboratory whose staff was totally dedicated to conducting whole effluent toxicity tests, backed by strict quality control procedures, and to offer the client a competitive price for these tests.  Today, we have remained true to form, adding only microbiological analyses to our list of services.  All of our freshwater test organisms are raised in-house and our marine test organisms are obtained from the highest quality suppliers.  Bio-Analytical Laboratories is accredited in accordance with the NELAC Institute and holds certifications in Arkansas, Louisiana and Texas.  We have clients throughout the United States and Canada, including but not limited to municapilities, chemical manufacturers, pulp and paper industries, refineries, steel manufacturers, poultry processors, universities, laboratories and consulting firms.  Bio-Analytical Laboratories is the only biomonitoring laboratory in North Louisiana.
