Mycobacterium tuberculosis presented via X Ray [4]

Diagnosis

If the patient is experiencing the symptoms described above it is highly likely they will be tested for the presence of Mycobacterium tuberculosis in their body. The evaluation process for a disease as serious as tuberculosis is a daunting one, but physicians need to be absolutely sure to produce a proper diagnosis. The steps for diagnosing a patient presenting with symptoms similar to TB include:

• Obtaining the patients’ medical history

• A thorough physical examination
• Testing for the presence of Mycobacterium tuberculosis
• Chest X-Ray or more in depth studies if needed
• Culturing of the samples taken from the patient
• Testing the Mycobacterium tuberculosis for drug resistance, due to possibility of having drug resistant tuberculosis (MDR TB) or worse, extremely drug resistant tuberculosis (XDR TB)
