Hi I am Dr.kadhir,
At first tuberculosis
is an infection that usually affects the lungs but some times they can also present as fever
of unknown origin. The main stream investigations are skin test, chest x ray
, blood tests ( IGRA'S), sputum for microscopic test to look for the organism in it and also for culture test ( that to see whether the organism is growing from the sputum).
The skin test, blood test and the chest x ray are not specific, though they can help in diagnosis when other infections are ruled out. Sputum microscopy and culture can confirm the diagnosis but they can be falsely negative.
Therefore TB can only be diagnosed on high index of suspicion with the help of skin test, blood tests and x rays or else can be confirmed by sputum microscopy.
It is better to undergo a sputum test as it would be more helpful for you.
There are quite lot of side effects ( eg: growth in kids, liver
disease, eye problems, neuropathy etc)for TB drugs and they are not uncommon.
It is important to have regular (monthly) follow up with your doctor for eye check up, blood tests like liver function tests. But they can managed appropriately with regular follow up.
Thank you for the consultation in health care magic.
