How is TB diagnosed Chest X-Ray Determines extent of the lung damage
{"Image DocumentName": "How is TB diagnosed? Chest X-Ray Determines extent of the lung damage", "Image ImageDescription": "Not a very definitive diagnostic tool. Another test to diagnose TB is through Chest X Ray. However, it must be emphasized that X-Ray results can only SUGGEST the extent of lung damage which may be caused by the TB germ or other microorganisms. Therefore, TB diagnosis CANNOT BE MADE through X-Ray results alone, except in very special cases. (Ex. TB germ is just starting to proliferate) In the picture, the arrow points out an INFILTRATION ( concentration of bacteria in an area) which suggests lung damage. This x ray result is consistent with TB, thus the patient should be recommended for sputum microscopy. In some cases however, people who have had TB in the past will show the same infiltration in their x ray even several years after their TB infection (like a scar). Therefore, medical records should reflect that the scar or infiltrate is a remnant of the past TB infection. As an application of this fact, individuals subject to pre-employment medical examination showing shadows / Infiltrates or scars consistent with TB should not be disqualified immediately but must be subjected to sputum microscopy to confirm TB status, unless previous x-ray results or treatment cards for TB can be provided to prove fitness to work. In the workplace setting therefore, employees showing CXR results consistent with TB during APE SHOULD be subjected to Sputum Microscopy for proper TB diagnosis.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
