Mastitis PCR Final Results Interpretation

• Positive Values:  Samples with CT values of 37 or less indicate presence of bacterial content and are reported as positive. Relative bacterial DNA content categories are classified as low (+), intermediate (++), high (+++)
  • Positive Pools: Additional testing may be performed to assist in identification of specific positive animals within a test-positive pooled sample. If multiple tests were performed, only the final result will be presented. Individual samples from pools that have positive Ct values (+, ++, +++) will be unpooled and retested upon request of the submitter. Follow-up testing is subject to normal testing fees.
• Suspect Values: Samples with values greater than 37 Ct do not meet the test criteria for positive samples, and are indicated as Suspect.
