Molecular LIS Articles & Lab Best Practices

A molecular LIS is a laboratory information system built for nucleic-acid workflows — PCR, qPCR, next-generation sequencing (NGS), and syndromic panels — where specimens move through extraction, plate-based batching, instrument interfacing, and structured variant or organism reporting rather than one-tube-per-test processing. The articles below cover how a cloud molecular LIS handles those workflows day to day, from accessioning through result release and billing.

Molecular labs put demands on an LIS that general clinical systems often handle poorly: parent-child specimen lineage through DNA/RNA extraction and library prep, plate map management with reusable well-assignment templates, instrument interfaces that return Ct values or per-target calls, bioinformatics handoff for sequencing data, and reagent-lot tracking that feeds QC. LIMS IQ treats each of these as a first-class workflow rather than a bolt-on module.

Where to start in this section

These posts are practical, workflow-level guides covering the decisions a molecular lab faces, from bench workflow through billing:

• Running the lab day to day — what a LIMS for molecular testing actually manages: accessioning, specimen lineage, plate and run workflows, QC review, reporting, and billing handoff.
• The NGS workflow end to end — how a sequencing run moves from accessioning through extraction, library prep, sequencing, bioinformatics handoff, and structured variant reporting, and where the LIS holds the record at each step.
• Reflex and rules-based testing — how the cascade from a screening PCR or panel result to a confirmatory test is designed and audited, backed by rules-based resulting and autoverification.
• Sample management end to end — accessioning, storage location, chain of custody, and tracking from receipt to disposition, including the derivatives and aliquots extraction produces.
• Cell line and research-sample inventory — how hierarchical storage, aliquot and derivative lineage, and scanned moves keep long-lived biological materials traceable across facilities.
• Antibody and reagent inventory — how a molecular LIS ties reagent lots, expiration dates, operators, and QC outcomes to each batch, so a recall can identify every affected result.
• Billing and the revenue cycle — how clean charge data moves from accessioning into billing and clearinghouses, including panel-level coding, eligibility checks, claim submission, and denial feedback for molecular labs.

How plate-based batch work changes the LIS

Most clinical LIS software is built around one specimen resolving to one result. Molecular labs run in plates, and that difference reaches into every part of the system — including the nucleic acid based tests an FDA-cleared assay or a laboratory developed test has to document. LIMS IQ handles the batch as a first-class object:

1. Reusable plate templates — 96-well, 384-well, or custom column × row layouts designed once in a drag-and-drop well editor and reused per assay.
2. Purposeful well assignment — each well designated sample, QC, or blocked, with QC materials and levels placed at fixed positions or automatically after the last sample, and configurable replicate counts.
3. Multiplex targets per well — reagents and per-well analyte targets assigned so multiplex assays measuring different analytes at different positions still resolve to the right result.
4. Defined processing steps — the sequential steps a plate follows (extraction, amplification, detection) built into the template, so every plate is tracked through the same workflow.
5. Full traceability — imported result-file batches linked back to the plate, reagent lots assigned to QC wells, and an audit trail behind each completion, retest, rejection, or flag.

Underneath the plate sits the same platform backbone: instrument integrations for PCR and sequencing analyzers, QC management across batch runs, and the test catalog and reference ranges that define what each target means.
