Few areas of
medicine are evolving as rapidly as molecular testing, and virtually no
area holds so much promise for altering the practice of medicine. Of
course, testing based on molecules has been conducted from at least the
time when physicians tasted urine to detect glycosuria. Today
multiparameter automated chemical analyzers have greatly extended the
ability to test for hundreds of compounds in any sample of the human
body. But the term molecular genetic testing now refers
specifically to nucleic acid analysis, usually involving DNA. The
techniques have become so sophisticated and numerous that increasingly
the average physician can have no more understanding of molecular
genetic testing than of the inner workings of the instrument that
performs a chem-18. However, several points warrant emphasis: the scope
and impact of molecular testing continue to expand, organized medicine
must ensure the highest quality of the molecular testing process, and
what comes before and after most molecular tests (the preanalytic and
postanalytic aspects) are often just as important as the test itself
