The Marine Laboratory is a member of the National Association of Marine Laboratories. Nurses work as researchers in laboratories, universities, and research institutions. ESA LAB@ refers to research laboratories at universities. These data are measured through spectrophotometry reports at certified testing laboratories worldwide. There exists some overlap between medical genetic diagnostic laboratories and molecular pathology. There are over 300 doctoral programs that collaborate with 1200 research laboratories and centers. Therefore, they were accessible for individual laboratories and research projects. The New Central Research Laboratories were completed in 1975. Prior to 1910, research mainly consisted of private individuals tinkering in their own laboratories. Pland Stainless make large sinks for laboratories and hospitals. ELISA tests also are used as in "in vitro" diagnostics in medical laboratories. Additional organizations included the "Corporate Research Laboratories". They also wanted to add more testing centres by inclusion of private laboratories. Both can serve as medical directors of CLIA certified laboratories. The Wellcome Tropical Research Laboratories opened in 1902.
