Laboratory Participation Rates and Volume
Of approximately 10,500 total labs (including hospital labs, large labs, public health labs, federal labs and other labs), 3,175 (about one third of the labs) were sending reports electronically in 2013. This compares to 2,864 labs in 2012.
As shown in the following graph, some lab types have more volume than others, generating a large percentage of laboratory reports from a small number of labs. Other lab types, while more numerous, send a smaller volume of laboratory reports.
