Control time reading with Delvo®Scan

The Delvo®Scan system referrals in this document are for the ver. 5.08 with Epson scanner V600. 

  • Read the ampoules immediately after the established incubation period is finished. If not possible to read immediately the resutl, remove the ampoules from the incubator and, cool them in cold/iced water for 5-10 minutes.
  • Dry the ampoules when using a water bath prior inserting into the grid. 
  • Insert the ampoules in the dedicated grid to read them at Delvo®Scan.
  • To determine the Control Time, you should choose the time of the ampoule where the Z value is the closest to -7 and not lower than -9 or higher than -6. Z-values around -9 or lower for blank milk means the incubation time has been too long if reading at control time is desired. The Z value cutoff between positive and negative samples is 0.
  • Register the Control Time found and use that time for the incubation of the ampoules of the same batch. (Note: during the test kit shelf life the time (CT) may become longer).
