- C & S Test: Purpose and How it Works
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Our youngster recently went through a bad siege, with high
- temperature and a serious infection. During one examination, the doctor took
- a swab, and ran it through the back of our son's throat. When he handed it to
- the nurse he asked her to get a "seeness" test. I have always wondered what
- that meant, and now that all is well, have time to write and ask you. Can you
- tell me something about the purpose of this test and how it works? I have
- been unable to find it in my home medical guide and am most curious. Thank
- you for your help.

- ANSWER: I must admit I was confused too, until I put things into perspective
- and kept repeating your name for the test over and over. It finally became
- clear that you were referring to a bacterial test called a "C and S", an
- abbreviation for "Culture and Sensitivity". It was used to determine the
- identity of the germ that was infecting your son, and to establish the most
- effective antibiotic to fight the infection. The swab is smeared on a
- material (usually agar) that permits the germs to grow rapidly (culture).
- They then can be placed on a glass slide, stained and viewed under a
- microscope to identify them. The agar plate also contains as many as a dozen
- samples of various antibiotics, carefully arranged around the circumference.
- When a clear space is observed around an antibiotic sample, it shows that the
- bacteria can not grow there, and demonstrates that this antibiotic is useful
- in fighting the infection (sensitivity).
