Is there a routine test to detect and monitor mold/bacteria levels in saline implants?

Unlikely that your implants are growing mold.  Not worth it to investigate.  I recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with and who is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery.

The risk of having bacteria/mold in your implants is extremely low and should not cause you to feel you must remove your current implants and replace them as long as everything is going well.  The current standard for filling saline implants is to do it  through a "closed system", which means a sterile IV bag is connected to a sterile IV tubing which runs the sterile IV fluid into your sterile implant.  As long as there are no breaks in sterile technique during the procedure, you can feel confident this fluid is sterile.   If you wish to replace your current implants, you can proceed with the same confidence level you had for your 1st augmentation.  See a board certified plastic surgeon to discuss this in detail.  Best wishes.

There is no significant danger to leaving your saline implants in place so a decision to replace them should be based on whether you have issues with how they appear or feel. The possibility of mold or bacteria in saline implants is extremely low, and virtually nonexistent after the use of closed fill systems became routine about 20 years ago. Surgery to replace the implants has a low risk.

Unfortunately, there is a lot of misinformation on the internet that can lead patients to be needless worry.  I have personally seen one implant in twenty years of practice that had grown mold.  This is an extremely rare occurrence and would require a break in sterile technique.  Please rest assured that you do not need to worry about this.
