What method can be used to determine the effectiveness of an antibiotic?
Microbiological assays. A classic method for detecting the presence of antibiotics is the use of microbiological assays that employ antibiotic-sensitive species of bacteria to determine whether specific antibiotics are present in a given sample and, with limited sensitivity, their concentration.
Which of the following diagnostic methods is the most applicable for checking the effectiveness of different antibiotics against a bacterial pathogen?

How does gene expression affect medication?
The term “gene expression” is important because we’re talking about how much your genes influence your response to a medication. Much like the director of a play or movie, your genes give instructions to other parts of your body. One of the things your genes direct is the production of enzymes required to break down (or “metabolize”) the drugs you take. These enzymes influence how effective a drug might be for you and how likely you are to experience negative side effects. Your unique combination of genes is called your genotype. Your genotype can tell us if you will make more or significantly less enzyme than other people. These enzymes help break down the medications into substances that can be more easily excreted by the body. However, in some cases these substances can be active and some are even harmful before they are excreted. This partially explains why some people will get no effect at all while others end up in the hospital with severe side effects from the same medication at the same dose.
Can pharmacogenomic testing cause harm?
However, promoting pharmacogenomic testing with application to only one disease state or with questionable testing practices can cause more harm than good. Most genes influence how the body metabolizes not just one class of medications, but can influence many other drug classes as well, and to different degrees.
Can genotype affect medication?
Overstating the impact of the genotype on the person’s ability to metabolize medications can also cause serious anxiety. Patients have reported feeling scared to take any medications, even when they know that their condition will not likely get better without treatment.
