Question on sputum samples ? blood in

[crystaly]

Does anyone know if  drs can tell where blood in the sputum has come from eg. lungs or sinus  etc? I took a sample in last weeek because ive had a problem coughing thick sputum which is frothy and contains bright red blood! I,m due to have some lung function tests in march but was just wondering if the sputum tests will show where the blood came from I would appreciate some help on this as I am a bit worried.

the sputum tests wont tell where the blood came from... they'd have to do a ct scan or other type of testing along those lines to make sure there is no active bleeding.  id imagine a chest x-ray or CT would do it.

Thanks for your answers . I am due to have some lung function tests in msrch so I will just have to wait and see what the results are to those

the blood and sputum will be analyzed for and infections.
one thing the doctors will look for is tuberculosis, due to frothy bloody sputum, but then again if had sinusitis before where ill cough up a little blood,from sinusis though.have you had night sweats cough lingering for over a mo. also a chest xray will see any abnormalities in the bil upper lobes of lungs. if not i would not worry. if all youve had is sinusitis for a more than a few days the irritation will cause bloody sputum. take care
