Five checks adapted from AAOIFI screening standards: business activity plus four balance-sheet ratios. All five must pass for ethical clearance. Every figure is arithmetic on public accounts, not judgement.
The Ethical ReadWhy It Falls Short, in Plain English
Quest Diagnostics's business is in a permissible area, but its interest-bearing debt is about 41% of the company, well over the ~33% line, so it does not pass on the financial screens.

The Business, in Plain WordsQuest Diagnostics trips on its own debt
Picture a routine blood test or cancer screen, the kind millions rely on each year. Quest runs those labs across the US and pulls in steady demand, yet the business still fails our ethical screen on debt ratio. That single red flag is enough to keep us away even though revenue is growing 9 percent and ROE sits at 15 percent.
We pass because the ethical test comes first. A narrow moat and forward P/E of 18.1 times do not change the fact that leverage sits outside our limits. Analyst chatter and a modest gap to fair value cannot override that hard rule.
The real risk is that high debt leaves little room if volumes soften or reimbursement rates tighten. A 9 percent profit margin offers thin protection in a sector where pricing pressure never really goes away. Analysis, not advice.
