Tb Skin Test Contraindications
Tb skin test negative, quentform TB test negative, bone marrow biopsy results indicative of TB (reacts to ziehl niehlssen), PCR negative. How come?
No...actually: The zn stain is a broad stain for acid fast bacilli of which mycobacterium tuberculosis is one of many. The specific tests like quantiferon or the pcr test are against you having tb. The culture is the "gold standard" but you will need to wait for it. It might turn out be a cousin of TB and that too will grow out of culture. Stay on TB meds until they are certain of the AFB positive organism. ...Read more

2 TB skin tests. Bumps measured 15cm. RN stated I possibly have LTBI & ordered QuantiFERON Gold in-tube test. Could anything cause a false positive?
Not at 15cm, but...: The bump is more likely 15mm, because 15cm is 6 inches and HUGE. A 15mm bump on a screening test is big but may still be a false positive (a screening test means the patient has NO symptoms of tuberculosis). If a patient has contacted somebody with TB, or has current symptoms, she likely has a true positive unless her bump is due to past BCG vaccine. The Quantiferon-TB blood test is very accurate ...Read moreSee 1 more doctor answer

Depends on risk: If you have a recent conversion, meaning you were negative and now you are positive, a chest xray is done to see if you have the disease. sputum cultures are done if active disease is suspected based on symptoms and xray findings your doctor may decide to give you a medication to treat inactive disease. ...Read more

Yes: This skin test uses parts of the killed protozoan parasite. However it is only useful in cases of cutaneous leishmaniasis. If you have suspicion of visceral leishmaniasis(systemic) the test is useless and cannot detect internal disease. Serologic testing using Elisa or IFA can be useful.

Tb blood tested negative but TB skin testd positive, what is that mean? Continuous low grade fever, swollenlumpnodes, sore thrt, HIV PCR RNA negative.
Contradictory Tb tst: Quantiferon-TB(the blood test) and the PPD(skin test) are not recommended together. The quantiferon test has more sensitivity/specificity(measures for how good medical tests are) but the gold standard is culturing the bacteria from either tissue or sputum which should be attempted if their is clinical suspicion for TB infection. ...Read moreSee 1 more doctor answer
