Best Pathology LIS for Anatomic Pathology Labs
For pathology groups and small hospital labs choosing an anatomic pathology LIS. We read each vendor's own product pages, the CLIA rules in 42 CFR 493 and CAP's cancer protocol page, and checked every claim against the rule it serves: case and slide tracking, synoptic reporting, report content, retention and amended reports.
The verdict by use case
Best for a group going digital
Its own pages name the scanners it works with and show the LIS tracking every expected slide as scanned, pending or glass only before the pathologist opens the case.
Best for a group that bills its own cases
Its AP page describes a CAP synoptic template, a block log and a slide log, and the same platform carries LigoLab's billing module, so the case and the claim share one record.
Best for a step-by-step audit trail
Its Specimen Tracking module records every move with the date, time and user, and its e.Synoptic module is built on CAP's electronic Cancer Protocols.

The retention clock for slides, blocks and reports
Clinical pathology keeps most records for 2 years. Anatomic pathology runs on longer clocks, and they are the first thing to settle with an LIS vendor, because the report half lives in the software for a decade.
The glass and the paraffin sit in your storage room; the LIS cannot keep them. What it can keep is the record of where each block and slide went, and the reports themselves. CLIA asks you to retain or be able to retrieve the original report, “including final, preliminary, and corrected reports”, so an amended surgical report written today still has to be retrievable, in both versions, in 2036 § 493.1105(a)(6).
Two more lines in the same section catch small groups out. Tissue remnants are kept until a diagnosis is made on the specimen § 493.1105(a)(7)(iii). And if the lab closes, it must still arrange for its records, slides, blocks and tissue to stay available for the full periods § 493.1105(b). A practice selling to a hospital or winding down needs an export of every signed report, not a vendor contract that ends with the database.
Two years for blocks is the CLIA floor, not the whole answer
Your accreditor, your state and your own legal hold policy may ask for longer. Set the LIS purge rules, if it has any, from the longest of them, and never let a purge touch a pathology report younger than ten years.
Takeaway
What a pathology report must carry
CLIA lists seven things every test report must show. An AP report template has to place each of them, and a demo is the time to check, because templates are often built by the vendor's implementation team and signed off just before go-live.
| The rule asks for | Cite | Where it lives on an AP report |
|---|---|---|
| Patient name and ID number, or a unique identifier and ID number | § 493.1291(c)(1) | Demographics carried from the requisition or the EHR order, matched at accessioning |
| Name and address of the laboratory location where the test was performed | § 493.1291(c)(2) | The site that grossed and read the case, not the billing entity, when a group runs two locations |
| The test report date | § 493.1291(c)(3) | The sign-out date, plus a fresh date on every amendment |
| The test performed | § 493.1291(c)(4) | Surgical pathology, cytology, frozen section, each stain or IHC panel reported |
| Specimen source, when appropriate | § 493.1291(c)(5) | Part labels: site, laterality and procedure for each specimen in the case |
| Result and, if applicable, units or interpretation | § 493.1291(c)(6) | The final diagnosis, the synoptic block and the comment |
| Condition and disposition of unacceptable specimens | § 493.1291(c)(7) | Unlabelled jar, fixation problem or insufficient tissue, stated on the report |
The histopathology standard adds two AP-only lines. Tissue pathology reports must be signed by a qualified pathologist, and if the report carries an electronic signature, “it must be authorized by the individual who performed the examination and made the diagnosis” § 493.1273(d). So a resident or a transcriptionist must not be able to release a case under the attending's name. Reports must also use “acceptable terminology of a recognized system of disease nomenclature” § 493.1273(e), which is where coded diagnoses and synoptic pick lists help.
A proposed change, not yet law
CMS's proposed rule CMS-3478-P, published on 8 October 2026 (91 FR 64480), would add the CLIA number and laboratory name to test reports, among other changes. Comments are due by 7 December 2026. Nothing changes until a final rule is published, but ask each vendor how quickly it could add a field to every report template. Read the proposed rule.
Amended reports: what CLIA asks and what the LIS must show
Every pathology group amends reports: a laterality caught at the tumour board, a margin revised after deeper levels, an IHC result that changes the diagnosis. CLIA sets three duties when a reported result is wrong: promptly notify the person who ordered the test, promptly issue a corrected report, and keep both versions § 493.1291(k).
Maintain duplicates of the original report, as well as the corrected report.
CLIA has no section titled “audit trail”. The audit trail is how an LIS supports two rules that do exist: the test record must show the dates of testing and who performed it § 493.1283, and the original and corrected reports must both be kept § 493.1291(k). An addendum that adds information is a different thing from an amendment that changes a signed diagnosis; a good AP system labels the two differently on the printed report.
A signed diagnosis that can be overwritten
If an edit after sign-out replaces the original text with no retrievable copy, the lab cannot meet § 493.1291(k)(3). Test it in the demo: sign out a case, amend the diagnosis, then ask for the original as the clinician first received it.
Takeaway
Synoptic reporting and the CAP cancer protocols
The synoptic requirement does not come from CLIA. It comes from the College of American Pathologists, whose cancer protocols list the required elements for each tumour site, and from the American College of Surgeons Commission on Cancer, which, according to CAP, has required the protocols' required data elements in its approved cancer programs since 1 January 2004. CAP says reporting with its electronic Cancer Protocols (eCP; some vendor pages say electronic Cancer Checklists, or eCC) also helps labs meet its own Laboratory Accreditation Program. CAP's current protocols page.
The protocols change several times a year. CAP's release of 16 September 2026 changed 14 protocols: among them, the phyllodes tumour protocol became required for accreditation of malignant phyllodes tumours, and the GIST protocols were expanded to every GIST site. For an LIS buyer the question is not “do you have synoptic” but who loads each release, how fast, and whether a half-finished case keeps the version it started on.
Every system in the table except CGM AP EASY says it does synoptic reporting. LigoLab's AP page says it ships the CAP synoptic cancer template and a checklist built on it; Psyche's e.Synoptic module is built on CAP's eCP. Clinisys's third AP product, CoPathPlus, describes eCC reporting through the mTuitive and CAP eFRM/xPert tools (CoPathPlus page); we left it out of the table because Clinisys pitches it at the most complex AP operations, not small groups.
Takeaway
Digital pathology: what the LIS has to do
A scanner and a viewer make images. The LIS decides which case an image belongs to, which slides of that case are still glass, and what gets billed. When the two systems are separate, someone retypes a case number, and that is where a wrong-patient image starts. Three things to see in a demo:
- The slide barcode, the scanner file and the LIS case match without anyone retyping.
- The pathologist sees, before opening a case, which slides are scanned, pending or glass only, recuts and levels included.
- A rescan or recut ordered from the viewer lands in histology's queue in the LIS.
NovoPath's digital pathology page describes all three and names the scanners it opens (Leica, Hamamatsu, Philips, Motic and KFBIO). It also notes that in the United States FDA clearance for primary diagnosis attaches to the scanner and viewing setup, device by device, and that the lab validates the digital workflow before clinical use (NovoPath). LigoLab and WindoPath mention a scanner or imaging interface and the Orchard module page carries a digital pathology heading, but none of the three describes the workflow; the CGM AP EASY and PowerPath pages do not mention whole-slide imaging.
Remote sign-out is a proposed rule, not a current one
CMS-3478-P would allow virtual access under the CLIA certificate of the primary testing laboratory, except in cytology. It is a proposal published 8 October 2026; until a final rule appears, plan remote sign-out on today's rules. The proposed rule.
If you read Pap smears: the cytology records
Cytology carries record duties that surgical pathology does not, and an LIS that logs them saves the spreadsheet a supervisor otherwise keeps for the inspector.
Cytology numbers in § 493.1274
- Slides examined by one person in 24 hours, at most100
- Shortest workday for the full 1008 hours
- Review of negative gynecologic cases, at least10%
- Look-back on prior negatives after a current HSIL or malignancy5 years
- Workload limit reassessed at least every6 months
The lab must keep, for each person, the number of slides examined in each 24-hour period and the hours spent examining them § 493.1274(d)(3). Slides lent out for any purpose other than proficiency testing must be documented, and all slides must be retrievable on request § 493.1274(f). The look-back on prior negatives § 493.1274(c)(3) is a search the LIS can run in seconds if it links cases by patient.
NovoPath says its cytology module logs each cytotech's workload against the CLIA limit (NovoPath cytology); CGM AP EASY says its GYN cytology option pulls random cases for QC review; LigoLab lists five-year clinicopathologic correlation. All three are vendor statements we could not test. Read the full rule at § 493.1274 on eCFR.
How this comparison was made
We read each vendor's own product and module pages, the CLIA rules in 42 CFR 493 on eCFR, CAP's current cancer protocols page and the Federal Register notice of CMS's October 2026 proposed rule, last on .
A filled well means we verified the claim against a document we could read and link: the vendor's own documentation or a regulator's record. An open ring means the vendor says so in its own material, but we found no document to check it against. A blank well means we found nothing either way, which does not prove the product lacks it.
Verdicts are editorial: no vendor can buy a verdict position or displace another vendor. This page carries no prices and no ratings; ask each vendor for a quote and a demo on your own test menu.
On this page a filled well means a vendor document names the function: a module or feature page, or a product page that lists it as a feature. A solutions page, a marketing overview or a brochure that names it earns an open ring. We left out XiFin, whose LIS pages we could not read for this comparison, and the AP modules inside hospital EHRs, whose documentation is not public.
Questions labs ask
What is the difference between an AP LIS and the LIS a clinical lab runs?
A clinical pathology LIS is built around orders, analyzers and numeric results. An anatomic pathology LIS is built around the case: parts, blocks, slides, stains, the gross and microscopic description, a signed narrative diagnosis and its amendments. Some vendors sell both on one platform; in a hospital the two often come from different companies. For the clinical side, see the best LIS for small clinical labs.
Can a hospital lab use its EHR's pathology module instead?
Many do. The questions on this page apply the same way: report content under § 493.1291(c), both versions of an amended report under § 493.1291(k), ten years of pathology reports under § 493.1105, and block and slide tracking. PowerPath and CoPathPlus are pitched at labs that want more AP depth than an EHR module gives.
How long must we keep pathology slides, blocks and reports?
Under CLIA: histopathology slides 10 years and cytology slides 5 years from the date of examination, pathology blocks 2 years from the date of examination, and pathology test reports 10 years after the date of reporting (§ 493.1105). Your accreditor or state may ask for longer.
Does CLIA require synoptic reporting?
No. CLIA requires the report content in § 493.1291(c) and recognised disease nomenclature (§ 493.1273(e)). The synoptic cancer protocols come from CAP, and CAP says they help with its accreditation program and the Commission on Cancer's standards. If you are CAP-accredited or read for an accredited cancer program, treat synoptic as required in practice.
Why are there no prices on this page?
AP LIS pricing is quoted lab by lab and depends on interfaces and modules; CGM AP EASY, for one, offers per-case or fixed monthly pricing. Ask each vendor for a written quote on your own case mix. Our other comparisons are on the compare index.
What should we ask for in a demo?
Bring a real case mix: a multi-part skin case, a breast resection that needs a synoptic, a Pap with a prior negative on file. Then ask the vendor to amend a signed case and reprint the original, show where a block is stored and who checked it out, and pull a report from its oldest test case.
