I'm trying to understand the differences between the typhoid IgG IgM test and the Widal test. Can one of these tests detect typhoid better than the other? I'm not sure which test is more reliable or if there's any specific situation where one might be preferred. Could you explain this to me?

The Typhoid IgGIgM test is a serological test that detects the presence of IgM and IgG antibodies against Salmonella Typhi in the blood, indicating acute or past typhoid infection, respectively; this test is more sensitive and specific than the traditional Widal test, which detects agglutinating antibodies, and can be used as a replacement or complementary test, especially in the early stages of infection or in immunocompromised patients; both tests can detect typhoid, but the Typhoid IgGIgM test is preferred due to its higher accuracy and ability to distinguish between acute and past infections.

View allSo a monkey bit me last week, and I'm a bit unsure about what I should or shouldn't be eating right now. Are there certain foods that I'd need to avoid or be cautious about? I'm really curious to know if my diet needs to change because of this bite.
Your 40-minute run and sweating before the blood test likely impacted your fasting blood sugar reading. _Why Fasting Sugar is High_ 1. _Adrenaline and cortisol_: Intense exercise triggers the release of stress hormones, which can raise blood sugar levels. 2. _Dehydration_: Sweating can lead to dehydration, causing blood sugar levels to increase. 3. _Liver glucose release_: Exercise can stimulate the liver to release stored glucose, increasing blood sugar levels. _Consider Retesting_ Repeat the fasting blood sugar test after a period of rest and a normal diet to get a more accurate reading.

I'm wondering, how common is lymph node TB in India? And is it true that if someone has a relapse of lymph node TB, it always turns into the MDR form? I'm trying to understand how serious this could be.

I'm really worried about my wife. She was diagnosed with TB in March and started on the standard treatment, but now she's dealing with back and neck pain, and stiffness in both areas. I've had some general physicians suggest getting an X-ray of her spine to check for Pott's spine, while others are saying an MRI of the whole spine or a CT scan of the LS spine might be better. Can you help me understand what might be going on and which specialist we should see? I'm also confused about why she might have spine TB symptoms when she's already on meds for TB in her lungs.
Yes .MRI spine is advised to the patient for evaluating potts spine TB..If TB spine is present pt needs ATT for another 6 months ,since it is extrapulmonary TB.
