  Company Overview

CytoTest Inc. is a world's leading biotechnology company providing high quality, innovative and affordable molecular cytogenetics products and services. Our US headquarters are located in suburban Washington, DC, in Maryland, close to the National Institutes of Health (NIH), one of the world's leading centers for biological research. Our proximity to and interaction with NIH, along with spirited connections with our other strategic partners in the academic, biotechnology and clinical communities enables us to stay at the forefront of diagnostic medicine and closely monitor trends and developments in molecular cytogenetics. It also allows us to take a uniquely proactive approach to the development and validation of tests in response to new and anticipated needs of research and clinical pathology.

CytoTest Maryland Biotech Park IVD GMP Facility

We are currently specialized in the design and production of DNA fluorescence in situ hybridization (FISH) probes. FISH is a powerful technique designed to detect presence or absence, location, integrity and amount of genomic sequences in tissue samples or cells. Introduced in the early 1980s as a cytogenetic research tool, it is now the most important technique for the clinical diagnosis of chromosomal abnormalities.

Since its founding, the company has advanced its technologies from generating fluorescently labeled single nucleotides to the design and manufacturing of FISH probes. To date, we have successfully developed and tested a diverse series of DNA FISH probes for molecular diagnostic applications in oncology, personalized medicine, prenatal testing, theranostics and other areas.

Our pipeline includes probes for clinically validated as well as research-stage targets and custom-designed products. New products are added continually, in part derived from our internal research and development efforts but more often as a result of requests for the development of specific tests from our customers, especially in the areas of rare cancers and of companion diagnostics for novel therapeutics.

Our products are prepared for both research and diagnostic purposes in the US, in China and worldwide. All of our products are manufactured in accordance with relevant regulations, and are quality tested to assure they meet the highest standards. A multi-year optimization effort resulted in products with higher quality than other probes used in the industry. Moreover, we carefully follow scientific and technology advances, observe leading-edge discussions of diagnostic industry standards, certification and regulatory requirements, and stay alert for consensus shifts relevant to in vitro diagnostics (IVDs) and laboratory developed tests (LDTs).

With a multi-disciplinary team of passionate and dedicated researchers, Cytotest can carry out manufacturing at all scales and is able to offer solutions for a wide range of diagnostic testing needs, from standard probe production to flexible custom design. We also are forming strategic collaborations to develop molecular diagnostic tests for novel and rare conditions, unfilled diagnostic niches, and for marketing in underserved regions.

The mission of CytoTest Inc. is to transform human genomic discoveries into useful products, and to design, manufacture and validate genetic and clinical diagnostics reagents with the highest quality. Our central goal is the development of state-of-the-art yet affordable molecular cytogenetics solutions. We are dedicated to providing cost-effective products, convenient customer service and reliable technical support.
