Every Douglas Insights report is built from the demand side. This note summarises the process; the full description is on the methodology page.
Count the demand unit first
Each market has an underlying unit of demand: tests run, procedures performed, units shipped, seats licensed. The model counts that unit by country, using admissions data, trade statistics, installed capacity and other public records, before any revenue is estimated.
Price what is actually collected
List prices overstate most markets. The model applies realised prices net of contract discounts, bundling and repeat testing, drawn from procurement data and interviews with buyers and sellers.
Reconcile against the supply side
The demand-side total is compared with what listed vendors disclose for the same market. Differences are traced to specific segments and resolved item by item, and the reconciliation is described in each report’s methodology section.
Publish the split, not just the number
Forecasts state volume growth and price growth separately. A reader who disagrees with either assumption can change it and see the effect, because the licensed Excel model ships with every report.
