Eastern Laboratory Services (ELS) is a full-service, state-of-the-art dairy and water testing laboratory with facilities in Medina, Ohio, and Grand Ledge, Michigan. The laboratory serves dairy producers, processors, and other dairy testing labs throughout the Great Lakes and Midwest region, offering a comprehensive portfolio of analytical and diagnostic services. With a fully equipped testing facility and a commitment to prompt, timely, and cost-effective turnaround, ELS functions as an essential quality-assurance partner across the dairy supply chain, from individual farm operations managing bulk tank milk quality to large-scale processing facilities requiring regulatory compliance data. ELS's bacterial analysis capabilities represent one of its core service areas, covering the full range of quality indicators essential for dairy milk compliance and herd health monitoring. Tests performed include standard plate count (SPC), plate loop count (PLC), preliminary incubation count (PI), lab pasteurized count (LPC), bactoscan count (BSC), direct microscopic somatic cell count (DMSCC), and coliform count. In addition, ELS conducts drug residue testing, cryoscope testing for detection of added water, sediment testing, and HR-3 analysis. These comprehensive bacterial quality metrics enable dairy producers and processors to maintain regulatory compliance and high-quality milk standards at every stage of production. Component analysis is another foundational service at Eastern Laboratory Services, enabling clients to understand the full nutritional and chemical composition of their milk. ELS tests for fat content, total and true protein, electronic somatic cell count (ESCC), milk urea nitrogen (MUN), free fatty acids (FFA), solids not fat (SNF), other solids, total solids, lactose, casein, and freeze point depression (FDP). The laboratory also offers fatty acid profile analysis and testing for abnormal milk parameters. Beyond bulk tank sampling, ELS can analyze components from individual cows, providing dairy producers with the granular data needed for targeted herd nutrition management, feeding adjustments, and performance benchmarking. Eastern Laboratory Services provides mastitis culture analysis to help producers identify and manage udder health challenges within their herds. Culture testing identifies key pathogens associated with bovine mastitis, including Staphylococcus aureus, Staphylococcus spp., Streptococcus agalactiae, Streptococcus non-agalactiae, coliforms, Pseudomonas, and additional organisms. Accurate identification of the causative pathogen is critical for selecting appropriate treatment protocols and implementing effective herd biosecurity strategies, making this service a valuable diagnostic tool for dairy veterinarians and herd health consultants. Diagnostic testing at ELS extends beyond bacterial and culture analysis to include reproductive and disease management support for dairy herds. The laboratory offers pregnancy testing using both milk and blood samples, enabling flexible collection methods that fit a variety of farm workflows. ELS also performs testing for Johne's disease (paratuberculosis), a chronic progressive wasting condition with significant production and economic implications for dairy operations, as well as bovine viral diarrhea virus (BVDV) testing. These diagnostic capabilities allow producers and veterinarians to make informed, timely decisions regarding animal health, treatment, culling, and herd biosecurity. In addition to its dairy-focused services, Eastern Laboratory Services performs a comprehensive range of water analysis testing relevant to farm water supplies and general water quality compliance. The laboratory tests for Escherichia coli and total coliform bacteria, as well as a broader suite of water quality parameters beyond basic microbial indicators. Clients can access sample submission forms directly through the ELS website for both standard coliform and E. coli testing and more comprehensive water analysis panels, streamlining the submission process for farms, municipalities, and other water-quality stakeholders in the region. A distinctive service offered by ELS is the production and distribution of calibration standards for dairy testing laboratories and instrument operators. These standards cover component testing, organic somatic cell count (OSCC), milk urea nitrogen (MUN), cream, skim, and bacterial parameters. Calibration standard results are posted online each week and can be ordered directly through the laboratory's website, supporting other dairy testing facilities and producer-owned labs in maintaining accurate and consistent instrument performance over time. This standards program positions ELS not only as an analytical laboratory but as a technical resource for the broader dairy laboratory community. With dual locations in Ohio and Michigan, Eastern Laboratory Services is geographically well positioned to serve dairy operations across the Great Lakes states. The laboratory provides clients with online access to their results through the LabResults.net portal, enabling fast and convenient retrieval of test data. ELS further supports clients through streamlined sample logistics, including a UPS return shipping portal for sample containers and ice packs, reducing friction in the submission process. For dairy producers, processors, veterinarians, and testing labs seeking a reliable and technically comprehensive laboratory partner for milk quality, herd diagnostics, calibration standards, and water testing, Eastern Laboratory Services offers an integrated and efficient solution.
