Diagnostic Lab Other Information Services Revenue Mix measures the share of Quest Diagnostics net revenue from information-services activity outside the physician and hospital laboratory channels.

Quest Diagnostics reported 9% of net revenues from this category in 2025.

The three disclosed channel buckets summed to 98%

Physician laboratory services represented 71% of net revenues and hospital laboratory services 18%.

Adding 71%, 18%, and 9% gives 98%, leaving about 2% for other items or rounding within the issuer's broader revenue presentation.

Other information services were one-eighth the physician-channel share

The 9% other-services share was about 12.7% of the 71% physician share.

Use Diagnostic Lab Physician Channel Revenue Mix and Diagnostic Lab Hospital Channel Revenue Mix to preserve the customer-source mix.

The residual category is heterogeneous

The 9% figure can include several customer and service types.

It should not be treated as one homogeneous operating segment or payer category.
