Worming Schedule Calculator

Reproduce a completed equine laboratory fecal egg-count record from its source-owned whole egg count and method factor without generating deworming advice.

Use this result well

Inputs that matter
One de-identified completed equine fecal egg-count record scope and basis; responsible veterinarian, diagnostic laboratory, supervised laboratory or reviewed source plus report/protocol revision; exact horse/sample, collection/handling, laboratory method/version and source-reported egg-category context; source-owned whole counted eggs; protocol-owned EPG-per-counted-egg factor; and an optional independently transcribed same-sample EPG source/value
Output to expect
Preserved record ownership, reproduced eggs per gram, and optional signed, absolute and relative computed-minus-independent same-sample EPG differences
How it works
Validate every provenance field, multiply only the completed source's whole counted eggs by its explicitly supplied laboratory-protocol factor, then reconcile an optional independent EPG value that covers the identical sample, method and egg category
  • Confirm that horse/sample identity, collection/handling, laboratory method and version, chamber/reading rule, egg category, count, multiplication factor and independent value all belong to the same completed record. A value from another sample, method, date or category is not interchangeable evidence.
  • Use the result only for arithmetic and transcription QA. It does not identify species or life stages, diagnose disease, classify shedding, estimate parasite burden, establish drug efficacy or resistance, perform or interpret FECRT, or select a product, dose, route, treatment, quarantine or retest schedule; follow the responsible veterinarian/laboratory, current label and farm-specific control program.

Choose your path

Built around the job you need to finish

Reproduce and reconcile one de-identified, source-owned completed equine fecal egg-count laboratory record without generating parasite diagnosis, efficacy, resistance, treatment, dosing or scheduling advice.

Veterinary technician transferring a completed FEC report

Preserve sample and method provenance while checking the report's count-times-factor arithmetic.

Name the responsible veterinarian/laboratory and report revision, preserve the exact sample, collection, method and category, then copy the whole count and protocol factor.

Reproduces the source EPG transparently without the website deciding what the result means clinically.

Diagnostic-laboratory reviewer checking a transcription

Catch a numeric mismatch between a chamber worksheet and an independently transcribed same-sample report.

Enter the completed count and method factor, then add the optional independent EPG source/value for the identical sample and protocol.

Sees signed, absolute and relative differences while laboratory validation and interpretation remain external.

Supervised learner documenting a quantitative method

Practice complete source ownership, including explicit zero counts, without learning obsolete calendar rotation or unsupported clinical thresholds from a calculator.

Use the reviewed-training basis, document the method/version and handling context, enter the source factor and follow all four calculation steps.

Can explain the arithmetic and its limits, including why zero EPG is not parasite absence and why one record is not FECRT.

How it works

Preserve One Completed Laboratory Record

Copy the responsible veterinarian or laboratory, report/protocol revision, de-identified horse and sample context, collection/handling record and exact quantitative method. Do not combine a count or factor from another sample, date, technique or egg category.

One sample + one method/version + one egg category + one reading rule

Reproduce Only Source-Owned EPG Arithmetic

The factor must come from the responsible method because dilution, chamber, detection limit and reading rules vary. A zero count remains a source record and does not prove that a horse is parasite-free or free of disease.

EPG = Whole counted eggs × Protocol EPG-per-counted-egg factor

Reconcile Without Clinical Interpretation

An optional independent source/value must cover the identical sample, method and category. The signed difference checks arithmetic or transcription only; it does not classify shedding, disease, efficacy, resistance or treatment need.

Difference = Reproduced EPG − Independent same-sample EPG

Updated: August 2026

Example Scenarios

Copy a completed chamber worksheet with 20 counted eggs and the exact report method's 25-EPG-per-egg factor. The worksheet reproduces 500 EPG while keeping the laboratory report authoritative.

Compare the reproduced EPG with an independently transcribed value from the identical sample and method. Inspect a nonzero difference against the original records instead of turning it into a treatment conclusion.

Enter an explicit source-owned zero whole-egg count and the protocol factor to reproduce zero EPG. The result remains a method-specific record and does not claim parasite absence or rule out clinical disease.

FAQ

No. It deliberately generates no drug, dose, route, treatment interval, quarantine or retest schedule. Current AAEP guidance rejects blind rotational deworming and fixed year-round intervals; use the responsible veterinarian, laboratory, current product label and farm-specific parasite-control program.

From the exact completed laboratory method or worksheet. Quantitative techniques use method-specific dilution, chamber and reading rules, so this worksheet requires the responsible source and never supplies a universal factor.

No. It reproduces zero under one completed sample and method. FEC does not detect every parasite or life stage, and AAEP states that FEC should not be used to diagnose clinical disease.

No. FECRT is a structured veterinary field test with sample-size, timing, method, host, drug and parasite-specific analysis. This worksheet handles one completed count-times-factor record and does not calculate or interpret FECRT.

A numeric difference is meaningful only when both values describe the identical sample, egg category and laboratory protocol. Agreement checks transcription and arithmetic; it does not validate the test or authorize a clinical decision.

About Worming Schedule Calculator

Reproduce the eggs-per-gram arithmetic in one de-identified, already completed equine veterinary or laboratory record. Preserve the exact sample, collection and handling, method/version, source-reported egg category, whole counted eggs and protocol multiplication factor, then optionally compare one independently transcribed EPG value from the same sample. This is laboratory-record arithmetic, not parasite diagnosis, shedding classification, total-burden estimation, drug-efficacy or resistance testing, FECRT interpretation, treatment selection, dosing or scheduling.
