Is Quest Diagnostics, Inc. DGX stock Halal to invest in?

Yes, as of September 2026, Quest Diagnostics, Inc. stock (DGX) is classified as a Shariah compliant stock.

On the latest data, Quest Diagnostics, Inc. passes on every count: non-permissible income under 5% of revenue, interest-bearing debt and investments each under 30% of market capitalisation, and no preference share issue. The stock's current purification factor is 99.84%. Compliance is reassessed every month as updated screening data arrives, and a stock's status can change when new financial reports are released. You can always check the current status of Quest Diagnostics, Inc. and explore other Shariah compliant stocks in the Tabadulat app.

How often is Quest Diagnostics, Inc. DGX reviewed for Shariah compliance?

Tabadulat reviews Quest Diagnostics, Inc. DGX for Shariah compliance every month. Each review applies the AAOIFI Shariah Standard No. 21 methodology, screening the company's business activities, non-permissible income, interest-bearing investments, interest-bearing debt, and preference shares, against the company's latest available financial data. The process operates under the direct supervision of Tabadulat's dedicated Shariah Supervisory Board of Islamic finance scholars. Because compliance depends on financial ratios that move with market capitalisation and reported results, a stock's status can change from one review to the next. Monthly screening ensures the status shown for Quest Diagnostics, Inc. reflects current financial data rather than an outdated assessment, and Tabadulat app users are notified if a holding in their portfolio becomes non-compliant.

Does Quest Diagnostics, Inc. DGX pass the AAOIFI Non Permissible Income criteria?

Yes, as of September 2026, Quest Diagnostics, Inc. stock (DGX) passes the AAOIFI non-permissible income screen. Under AAOIFI Shariah Standard No. 21, income from impermissible sources (such as interest or Riba, conventional financial services, alcohol, gambling, or tobacco) must remain below 5% of a company's total revenue. Quest Diagnostics, Inc.'s income from non-permissible sources is currently within this 5% threshold. Even permissible levels of incidental impure income should still be purified: investors donate the corresponding share of dividends to charity, as reflected in the stock's purification factor. This screen is reassessed monthly using the company's latest financial disclosures.

Does Quest Diagnostics, Inc. DGX pass the AAOIFI Interest Bearing Investments criteria?

Yes, as of September 2026, Quest Diagnostics, Inc. stock (DGX) passes the AAOIFI interest-bearing investments screen. Each month Tabadulat compares Quest Diagnostics, Inc.'s holdings in interest-earning instruments, such as conventional deposits, bonds and treasury bills, against AAOIFI's 30% market capitalisation cap. The current screening shows the company inside the limit. Because the ratio is measured against market capitalisation, it can move with the share price as well as the balance sheet, which is why Tabadulat rescreens the stock every month.

Does Quest Diagnostics, Inc. DGX pass the AAOIFI Interest Bearing Debt criteria?

Yes, as of September 2026, Quest Diagnostics, Inc. stock (DGX) passes the AAOIFI interest-bearing debt screen. AAOIFI tolerates some conventional borrowing but draws the line at 30% of market capitalisation. On the latest data, Quest Diagnostics, Inc.'s interest-bearing debt stays below the line. Because market capitalisation changes daily, a company's debt ratio can drift toward or away from the limit even without new borrowing, which is why this screen is reassessed every month.

What is the dividend purification factor for Quest Diagnostics, Inc. DGX stock?

The dividend purification factor for Quest Diagnostics, Inc. (DGX) stands at 99.84% in the September 2026 screening. In plain terms, 99.84% of a DGX dividend is retained, and the remainder reflects incidental non-permissible income, typically interest on corporate cash, which Halal investors donate to charity (Tazkiyah). AAOIFI methodology asks for purification even on fully compliant stocks. The factor is recalculated with each monthly screening as new financial data arrives, and the Tabadulat app can help you calculate and track purification across your whole portfolio.

Does Quest Diagnostics, Inc. DGX pass the AAOIFI Preference Share screen?

Yes, as of September 2026, Quest Diagnostics, Inc. stock (DGX) passes the AAOIFI preference share screen. AAOIFI Shariah Standard No. 21 prohibits investing in preference shares because they grant holders guaranteed or priority rights to dividends and capital ahead of ordinary shareholders, a structure that conflicts with the Shariah principle that investors should share profit and loss in proportion to their ownership. Quest Diagnostics, Inc. has no impermissible preference share structure affecting its ordinary shares, so the stock is compliant on this criterion. Like all AAOIFI screens, this is verified in each monthly review.

September 2026: PASS

Quest Diagnostics is a leading healthcare company specializing in diagnostic information services, with a significant presence in the global diagnostics and research sector. The company provides laboratory testing services that are crucial for medical decision-making, serving physicians, hospitals, and patients. Quest Diagnostics processes one of the largest databases of de-identified clinical lab results worldwide, enabling it to deliver actionable diagnostic insights that support disease detection, treatment management, and overall healthcare quality. Before any of that matters to a Muslim investor, one question comes first: is Quest Diagnostics stock Halal?

Is Quest Diagnostics Shariah compliant?

Healthcare rarely troubles the activity screen; treating illness is permissible work. For Quest Diagnostics, the AAOIFI Shariah Standard No. 21 verdict turns on the balance sheet instead: research is capital hungry, and interest bearing debt and investments must each stay below 30% of market capitalisation.

Does Quest Diagnostics pass the business activity test?

Yes. In the September 2026 screening Quest Diagnostics holds an overall PASS, which a stock only earns when its core business clears the activity screen. Treating illness is permissible work; the scrutiny belongs to the financing behind it.

Is Quest Diagnostics' income Halal?

Yes, within AAOIFI's tolerance. Quest Diagnostics' income from non-permissible sources stays below 5% of revenue in the September 2026 screening, and the small impure portion is handled through purification: the factor of 99.84% tells holders of DGX what share of each dividend to keep and what remainder to donate to charity.

Does Quest Diagnostics meet AAOIFI's debt and investment ratio requirements?

Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation. Because the caps move with the share price, our Shariah Supervisory Board has DGX re-screened every month, and the result above always shows the latest verdict.
