The field of laboratory medicine is advancing towards the use of molecular techniques using DNA and RNA to aid in the diagnosis of genetic disorders, infectious diseases, and other diseases. In addition, molecular techniques also applied in pre-implementation screening. With the introduction of personalized medicine, molecular techniques are being applied for monitoring and deciding which therapeutic agent can be effective for treatment. An individual who is responsible to perform and interpret the molecular testing to aid in diagnosis is called a molecular diagnostics scientist (MDS).
Molecular diagnostics scientists work with a vast array of sophisticated lab equipment. Much time is spent on repetitive tasks that require fine motor skills such as being able to open and use very tiny test tubes and other tools.
Molecular diagnostics scientists work in labs of large hospitals. They typically work an eight hour shift with combined standing and sitting. The work day often starts very early. It is not uncommon for MDSs begin work at 5:30 AM.
