The verdict

GeneDx runs at 19% of its industry's injury rate - far safer than the typical Genetic testing laboratories workplace, earning a grade A.

GeneDx: 0.7 TCR = 19% of Genetic testing laboratories BLS 3.8 · 2y Form 300A (see methodology below)

GeneDx safety composite

GeneDx scores strongest on total case rate (tcr) (safer than 90% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

Where GeneDx falls in its industry

162 Genetic testing laboratories establishments

Safer than 90% of graded establishments in this industry, whose median TCR is 3.0.

Grade A

More dangerous than peersSafer than peers

Narrower to Maryland alone (the establishments it most directly competes with for workers and contracts): ranked #2 safest of 4 Genetic testing laboratories employers in Maryland.

GeneDx (371 employees, TCR 0.7) among 29 same-industry peers, split at the industry median of 154 employees and a TCR of 3.0

GeneDx has more employees than the Genetic testing laboratories median and a lower injury rate than the industry's median TCR of 3.0. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
