• Clinical Appearance
This refers to any specific signs and symptoms that are related to the development of an infection or disease. The appropriate description of the clinical appearance often leads to a diagnosis of the illness.
• Stained culture/histology examination
False coloration of a substance to aid in the inspection of tissues, microorganisms, or other cells under a microscope.
• Tests for antibodies to the microorganism
Antibody tests rely on on the fact that there are specific antibodies for each antigen and each one can be used to determine the presence of the other. For example, a known antigen can be added into a blood sample and if the matching antibody exists in the sample, they will bind together. These tests are typically …show more content…
Also, to make primers for the PCR test, some previous sequence data is required. Therefore, PCR can only be used to identify the presence or absence of a known pathogen. Another drawback is that the primers used for PCR can strengthen non-specifically to sequences that are similar, but not entirely identical to the specific DNA. In addition, incorrect nucleotides can be combined into the PCR sequence by the DNA polymerase, but at a very low rate.
• X-Ray
The X-Ray is an extremely common procedure that allows visuals of the inside of the body without requiring any incisions. X-rays are done in a radiology department, a dentist’s office, or in certain clinics. The radiologist will position you to get the best view of the injured area. Some images may be taken while you stand in front of or lie down on a specialized plate or table that contains X-ray film or sensors.
X-rays do use a small amount of radiation but the level of exposure is safe for adults but not for a developing fetus. If you are getting an X-Ray because of an injury you must move the injured area to get the best picture resulting in even more discomfort to the area. Sometimes a dye is required to perform the test to get a better image which could cause some side effects to certain
