How to Set-Up and Conduct an Acid Fast Stain
Acid Fast stain – Ziehl Neelsen

Every year, a collaboration of 18 national clinical laboratory organizations honor medical laboratory professional by declaring the first full week of April as Medical Laboratory Professionals Week. In step with the professional organizations, Ethos Bioscience appreciates the invaluable service these professional make to healthcare across the globe.
Our Ethos Biosciences team manufactures the biological dyes, stains, and general reagents used by laboratory professionals and pathologists for cytology, histology, and microbiology procedures. Our team includes laboratory professionals that test our products to ensure they will perform as needed to get the information essential for informed medical decisions. We also supply accessory materials such as embedding and mounting media, hematology buffers, and supplies for specimen preparation and processing.
Medical lab professionals use highly specialized instruments to analyze samples like tissue, blood, urine, and bodily fluids that not only require technical knowledge, but also a bit of artistic talent. Whether they’re in a clinical facility, in a hospital, or at a research organization, the information gleaned by lab professionals is essential for timely information to facilitate medical decisions.
Medical Lab Professionals generally never meet a client face-to-face and often work directly with a practitioner. That’s because testing can take place across a variety of locations, most often in a hospital, an independent reference lab, a public health laboratory, home testing, direct access testing, and point-of-care (POC).

Unlike the name suggests, there are a large number of professions that are part of the medical laboratory community, and they impact many applications, including human pathology, veterinary pathology, clinical research, and in vitro diagnostics. Our most common products are here to support their work, and, at Ethos, we can say ‘We’ve got a product for that!’
