Call preparation · editorial guide

Make the call count.

Find laboratory and diagnostic-test contacts for orders, kits, results, billing and support. Confirm the performing lab and test before sending documents or specimens.

Have ready in your secure workspace

  • Lab and test name from the order or bill
  • Ordering practice and existing order reference
  • The specific administrative question

Questions to resolve

  • Is this the performing laboratory and correct support team?
  • What secure channel handles this order, result or billing question?
  • Are there test-specific submission or specimen instructions?

This is a general administrative checklist, not payer policy or advice about a particular patient. Confirm the current plan instructions.
