What this actually is

You bring your specialist expertise to AI evaluation. The shape of the work varies but the pattern is the same: review outputs, rate quality, write prompts, flag errors. The platform title (Domain Expert - Healthcare(DendiLIS)) reflects the rate band and the expertise required, not the day-to-day work.

Original posting from Mercor

To qualify you must use Dendi LIS or another laboratory information system regularly - weekly or more - as a working part of your job, with 2+ years of experience in a CLIA-certified clinical laboratory.

Core (required of all candidates)

  • Knows how to work accessioning end to end: order entry, specimen labeling, requisition and insurance capture, and specimen rejection criteria
  • Knows how to review results before release (QC status, delta checks, critical values, instrument flags) and when a result must be held
  • Knows how reflex and confirmation testing work (for example, screen-positive to confirmation in toxicology) and when one should have been triggered
  • Knows how to trace a specimen and its chain of custody through the lab, and catch mislabeled or mismatched specimens
  • Knows how corrected and amended reports work, and who must be notified when a released result changes

Specialized depth (strong working knowledge in at least 2-3 of the following)

  • Toxicology (immunoassay screening, LC-MS/MS confirmation, cutoffs)
  • Molecular, PCR, and infectious disease testing
  • Pharmacogenomics (PGx)
  • Clinical chemistry and hematology
  • Instrument interfacing and LIS configuration (test codes, panels, reference ranges)
  • Billing and medical necessity (CPT, ICD-10, ABN)
  • CLIA and CAP compliance and inspection readiness

What you'll do

  • Confirm that an accession, result, or report in the LIS is correct and releasable, not just entered
  • Catch results released despite a QC failure, missed reflex or confirmation tests, mismatched specimens, and changes to records the task did not ask to touch
  • Judge completeness: are all tests on the order, all specimens, and all required notifications handled
  • Distinguish "the LIS accepted it" from "a lab director would sign off on it"
  • Verify that a request that should be refused (releasing a result with failed QC, editing a released result without a corrected report) is refused rather than forced through

Requirements

  • Frequent use of Dendi LIS or another LIS (e.g., Orchard Harvest, Epic Beaker, Sunquest, Cerner PathNet, LabWare, XiFin) - weekly or more - in your current or recent role
  • 2+ years of experience in a CLIA-certified clinical laboratory
  • Can spot a QC failure, a missed reflex, or a mislabeled specimen on sight
  • MLS/MT (ASCP) certification or equivalent state licensure; lab supervisor, LIS analyst, or lab director experience is a plus
  • Strong working knowledge in at least 2-3 specialized areas above
  • Prior data annotation, labeling, or AI evaluation experience is a plus
