Miliary Tuberculosis (TB)
Diagnosis of Miliary TB
Examination and culture of a sample from the infected area When available, nucleic acid amplification tests Skin test for tuberculosis or blood tests to detect tuberculosis A chest x-ray Diagnosis of miliary tuberculosis is similar to the Diagnosis . Samples of infected fluids may be examined under a microscope and/or sent to a laboratory to be grown (cultured) and tested. Samples may be Blood Cerebrospinal fluid, obtained by Spinal Tap (lumbar puncture) Urine Fluid from the space between the two layers of the membrane that surrounds the lungs (pleura) Fluid from the space between the two layers of the membrane that surrounds the heart (pericardium) Joint fluid Bone marrow Mycobacterium tuberculosiscan sometimes be identified by doing nucleic acid amplification tests (NAATs) on certain types of samples. NAATs look for an organism's unique genetic material, its DNA or RNA (which are nucleic acids). NAATs use a process that increases the amount of the bacteria's DNA or RNA so that it can be more easily identified. The Skin test for tuberculosis or blood tests to detect tuberculosis ( A chest x-ray may show the thousands of small spots that are typical in miliary tuberculosis. Other imaging tests are done depending on which areas of the body are affected. They may include computed tomography (CT), ultrasonography, and magnetic resonance imaging (MRI).
