Many Lyme specialists believe that a single Lyme-specific band, along with clinical presentation, is sufficient to diagnose Lyme disease (with an acknowledged 3% false positive rate).

The US Centre for Disease Control (CDC) has stipulated that certain "bands" in the Western Blot test must be positive in order for a Lyme test to be declared positive - the problem is that these bands were chosen for statistical, rather than diagnostic criteria.
