Hi; yes it makes considerable difference how soon they are checked for gram

stain (negative or positive), how soon the culture is started, and whether they

use the more common Kirby-Bauer Method, or the special agar slants used

in Synergy testing (this has to be sent to Saimens, M.D., Medical College,

Synergy Laboratory, Columbia University in New York City). If they fail to

handle

them properly, as you have found out, the results are null--which is why so many

cf doctors assume they cannot get a valid culture unless they suction the

patient

or do a bronchoscopy--not that there are not valid other reasons for doing those

procedures. I have seen the variation in my own experience and have certainly

heard about it from other adults with cystic fibrosis, including my own youngest

(ahem!) adult wcf. I hope that this helps somewhat; for some reason, I had

trouble

pulling up the links and web sites from Internet Explorer tonight, so decided to

just

summarise it myself, which I hope you do not mind. May things be better for you

in the coming New Year, n Rojas, wcf, mom of 3 ADULTS, the youngest of

whom has cystic fibrosis, too

sputum cultures

Does anyone know information about the right way sputum cultures should be

handled. How long can they be left out, how long do you have to get the

best results. I just want some info so I can have our doc call and

hopefully have it set up so we can use the hospital lab instead.

Just found out our lab does not even plate them till late, around 6-7pm. No

wonder he has never grown anything out at that lab, only the hospital lab.

Thanks

I dont know how long you can leave them out, but I don know they save

the sputum cultures.It took a long time for PA to grow in Tyler's.My

cf nurse was discussing which cup grew what, and the last one he had

done still took (i think) a few weeks to grow.Hope this helps.

Dear Darci,

I am not clear on what lab your hospital is, but CFsputum clutures should always

be done at a CF center. Most labs don't have the proper medium to grow the

rather unusual and exotic bugs many pwcf have. I don't know the answers to your

other questions except that it often takes at least 5-7 days to get results so

if you are getting them any faster they probably aren't accurate.

I hope this helps a little,

love,

M

Thank you for all the responses. We do not have a CF Center here. A CF doc

comes from Children's Oakland once a month. I spent 2 hours at the hospital

today setting up future sputum cultures. The other lab is through my

insurance, but they have me set up now as a clinic patient so my insurance

will pay. How scary to think that some labs don't even plate till 7pm. I

guess that is a good question to ask your lab from now on.
