No, Not a problem to share.
Once I sent my medical report at the first time, LVO assessed and they thought I had some kind of tb in my lung (There was one very small spot on my lung site). so they sent me and my DMP a letter to repeat chest xray (VO mentioned a date to do xray) and sputum culture. All requests came from VO but not from DMP. VO advised to culture sputum for 6-8 weeks. My DMP cultured for 7 weeks and produced report as there was no growth. My xray was cleared this time (there was no spot).
8 weeks was the highest time for spuutum culture as vo mentioned in the letter. If there is any bacterial growth, it should start in the first week. So if there is no growth in second or third week, you can assume you dont have bacterial activity in your lung. But DMP or VO advised to keep it 6-8 weeks to make sure that you definitely do not have any sign of bacteria in your lung.
Vo ask for repeat chest xray after certain date so that VO can see the difference in between two xray plate. If there is any bacteria in your lung, you can see more white spot in your lung, it means you have active bacteria in your lung.
Hope it helps.
Cheers Buddy.
