1905 Otto Folin in biochemistry lab at McLean Hospital

20th Century to Present – Different Objectives – Different Tools

By the turn of the century physiological, pharmaceutical, forensic, public health, and microbiological laboratories were in existence. The use and number of analytes found in blood for clinical diagnosis and treatment was expanding. This is evidenced by the fact that in 1900 Dr. Otto Folin became, in its modern sense, the first full-time biochemist in the United States. In 1908 Todd and Sanford published the first edition of their book Diagnosis by Laboratory Methods. In addition to procedures for laboratory testing, the manual described general techniques for obtaining blood by venipuncture and skin stick. By the 1920’s the use of venipuncture for diagnostic testing had become widespread. The term phlebotomy was taking on a whole new meaning.
