Thanks for your question on Health Care Magic.
I can understand your concern.
Chest infection is commonly caused by bacteria.
And so best treatment of
lung Infection is depending on species of bacteria.
So identification of causative organism is very important in treatment of lung Infection.
By this we can also guide antibiotic therapy.
So in your mother's case, I will advise to get done
sputum culture and sensitivity report.
Culture report will isolate the causative organism. And sensitivity report will guide us about effective antibiotic treatment.
By this we can fasten the recovery and prevent
drug resistance.
Her current antibiotic (
amoxicillin) might not be working on the organism.
So better to get done sputum culture and sensitivity report.
Hope I have solved your query.
I will be happy to help you further.
Wishing good health to your mother. Thanks.
