Aaah. Ok. That makes sense. My API always comes back as 'indistinguishable'. Maybe the reagents aren't fresh.. I am not sureHello Dave, please be aware that the ABC tests you have been using are in the beta testing phase as stated on the app, and may not be functioning correctly on all devices. We would suggest using alternative test kits to obtain accurate results. Our recommendations are as follows:
- KH: RedSea or Salifert
- Calcium: API
- Magnesium: RedSea or Salifert
Thank you and have a great day!
