Domain Expert - Healthcare(DendiLIS)

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
