Bulk-Tank Testing

• Heater Block Temperature: 45°C ±5°C.
• Colour must appear on the temperature strip for 15 minutes before starting the test
  
  

• Do not open the foil or put kits on the heater block until ready to run.
• Be sure a coloured pellet is at the bottom of the tube.
• The device must be prespotted with control, sample and activation spots.
• Devices should be stored at 0°–7°C.
  
  

• The sample should be well-agitated, raw, commingled bovine milk.
• Incubate the sample for 5 minutes (6 minutes maximum).
• Pour the sample onto the device; it should take approximately 30 seconds to reach the activation circle. The sample flow should never take more than 1 minute. *Watch the device during this critical step.
  
  

• Snap the device as the activation circle BEGINS to disappear—DO NOT wait until activation circle has completely disappeared before snapping.
• Leave the device on the heater block for the 4-minute colour-development time.
• Do not attempt to read the device:
  • Before the full 4 minutes
  • If the control and sample spots are not uniformly developed
  • If a high blue background has occurred
