TROUBLESHOOTING
Essential Tips
for Your Lab
My product arrived damaged or compromised
If a product is punctured, leaking, discolored, expired, or otherwise looks wrong—don’t use it. Contact your distributor or Biomed Diagnostics directly for guidance or replacement.
Nothing is growing in the culture
Double-check these:
• Was the sample properly collected?
• Was the device sealed and stored correctly before use?
• Is the incubation temperature and time within spec?
Some organisms take longer to grow. Refer to the specific product insert for incubation guidelines.
The colors look off in my chromogenic media
Unexpected colors can result from:
• Off-target organisms
• Overgrowth
• Contamination
• Misreading timing or lighting conditions
When in doubt, sub-culture or confirm using additional methods. Refer to the included wall chart or product insert.
My BHBCheck Plus Meter isn’t giving readings
Make sure:
• You’re using compatible test strips from the same lot
• The calibration strip has been used properly
• Batteries aren’t dead
• The test strip is fully inserted
Still not working? Check the user manual or contact us.
I can’t transfer data from the meter
Make sure you’re using the BHBCheck Plus Data Transfer Cable and Biomed’s free software. If you’re still having trouble, refer to the user manual or contact us for support.
Can I reuse a pouch, tray, swab, or plate?
No. All Biomed devices are single-use. Reusing anything increases the risk of contamination and invalidates the results.
Field sample transport
Use designated Biomed tools like InPouch®, Transit Tubes, or PBS/Saline vials to keep samples stable during transport. Follow label instructions for temperature handling—many products are stable at room temp, but check first.
Shelf life and storage
Always check the expiration date. Store products according to their label—some are fine at room temp, others need refrigeration. Never freeze unless explicitly stated.
There’s condensation in the pouch or tray
Some condensation is normal depending on temperature changes. If media appears discolored, murky, or flooded, don’t use it. When in doubt, toss it.
