Hello! No it doesn’t. Many recommend am sputum since the secretions pool in your lung while lying flat during the night and are more plentiful for many patients at that timeHowever, they will see whatever bugs are in there at anytime of the day .

Thank you. I really appreciate you answering me. We are going to do a trial run of doxycycline for 14 days but I wanted to make sure that I submitted sputum sample first.

I meant to say wetter throughout the day.

Hello! You are welcome! As long as the mucus is mucus, not a lot of saliva. Yes, wetter produces the sputum which is needed. It is absolutely necessary to get the specimen before you start antibiotics. I hope that you feel better soon. I hope that you are taking probiotics and prebiotics with the antibiotics. Katie

My covid stay one morning I had sputum I knew it was infection. My pulmo came in and I told him his nurse looked at chart nothing there well guess what by labs next morning I had white count 19,000. Bacterial infection. We do know our bodies. I haven't had an infection for a long time I always have inflammation. Another thing I am on zpak 3 times a week which helps any infection and also inflammation.

Kandy,

Yes, we certainly get to know our bodies and when we get an infection. We must listen to our bodies, the warning signs

Hi Franny,

I just wanted to check in to see how you are doing. I agree with Katie that sputum samples don't have to be done in the morning, but it works for most people because we generally have a collection of sputum in our system in the morning and we don't have food, or other contaminants in our sputum. But if later works better for you, just don't do it right after eating or brushing your teeth.
