अक्सर पूछे जाने वाले प्रश्न

Can I order tests for patients in the United States?

Yes, with the right clinical wrapper. Consumer-initiated testing in the US requires an ordering clinician or a patient-authorized direct-access model depending on the state. We support both: bring your own clinician network, or use our clinical review partners.

How do results come back?

Three formats, all from the same order: a signed webhook event, a LOINC-coded JSON payload with reference ranges and abnormal flags, and a PDF report. FHIR DiagnosticReport export is available on the platform plan.

What does it cost?

You pay per test. Sandbox keys are free, and pricing in production starts at the listed catalog price with volume tiers from 500 tests per month. There is no setup fee and no per-seat licence.

How do you handle PHI and HIPAA?

PHI is encrypted at rest and in transit, access is logged, and we sign BAAs with covered entities. Data residency options exist for EU and UK customers under GDPR. Full details are on the compliance page.
