Heat map showing Lyme disease antigen reactivity. The positivity cutoff for each antigen was set at greater than 10 chemiluminescent units (CU) (shown as yellow or red). The color key is as follows: Red - High positive (CU > 20); Yellow, orange - Moderate positive (CU = 10.1–20); White - Negative (CU ≤ 10).
