Lyme season is upon us. In the last month, we've seen about 10 children with Lyme, including 3 with multiple rings.
Last year, the Connecticut Agricultural Experiment Station tested 3,240 ticks. About 90% of these turned out to be Idoxes (deer) ticks. 22% of these deer ticks wer positive for Lyme -- down considerably from 38% two years earlier.
When parents call us about a tick bite, many ask about getting the tick tested. A number of state agencies and commercial labs offer testing.
The one that seems to have been used most frequently is New Jersey Laboratories. Turnaround is about ten days; cost is $60.
But we don't generally encourage this for a few reasons:
1. Studies have shown that only about 2% of tick bites lead to Lyme. If a tick tests positive, that is certainly not a guarantee that Lyme will ensue.
2. Ticks transmit other bugs (Anaplasma, babesia, bartonella, and the latest -- Borrelia miyamotoi). Testing is available for them, but is pricey.
3. Some children get bit multiple times over the course of a summer. Testing can quickly become impractical.
