| Special Instructions: |
Patient's infecting organism needs to
be saved in order to perform this test. Most isolates at least one week from
date of culture. If the isolate has not been saved, the procedure cannot be
done. The ordering physician must specify the collection date (or culture
number), culture site, time of antibiotic dose (peak or trough), and pathogen to
be tested. Two serum samples are usually collected for performing the serum
killing test (schlichter). The trough is obtained just before the next dose of
antibiotic; the peak is obtained anywhere from 15 minutes to 1 hour immediately
following the antibiotic dose, time dependant on method of dose. Results: MID
(maximum inhibitory dilution) is expressed as the highest dilution of patient's
serum that will inhibit growth of a specific pathogen isolated from that
patient. MBD (maximum inhibitory dilution) is expressed as the highest dilution
of patient's serum that kills the organism. Contraindications: Organisms that
are too fastidious to grow in broth media will not be tested for serum killing
test. |
