Derived Specimen
1995-12-15
Definition: for some diagnostic studies -- especially in microbiology -- the initial specimen (e.g., blood) is processed to produce results (e.g., the identity of the bacteria grown out of the culture). The process also produces new "specimens" (e.g., pure culture of staphylococcus, and E. Coli), and these are studied by a second order process (bacterial sensitivities). This field contains codes that identify the parents (e.g., blood culture) and children (e.g., penicillin MIC) in such cases. The codes are the following:
