The verdict

MarDx Diagnostics runs at 74% of its industry's injury rate - safer than the typical In-vitro diagnostic substances manufacturing workplace, earning a grade B.

MarDx Diagnostics: 2.4 TCR = 74% of In-vitro diagnostic substances manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

MarDx Diagnostics safety composite

MarDx Diagnostics scores strongest on dart rate (safer than 84% of same-industry peers) and weakest on total case rate (tcr) (safer than 23%), 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 MarDx Diagnostics falls in its industry

201 In-vitro diagnostic substances establishments

Safer than 23% of graded establishments in this industry, whose median TCR is 1.4.

Grade B

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #43 safest of 50 In-vitro diagnostic substances employers in California.

MarDx Diagnostics (45 employees, TCR 2.4) among 29 same-industry peers, split at the industry median of 120 employees and a TCR of 1.4

MarDx Diagnostics has fewer employees than the In-vitro diagnostic substances manufactu median and a higher injury rate than the industry's median TCR of 1.4. 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.
