A duplex TaqMan qPCR assay built for cannabis cultivators.
Proactive, science-backed Aspergillus screening that catches
contamination at cultivation — not at compliance testing.
Compliance testing catches failures. We catch problems early.
Airborne spores spread silently.
Aspergillus conidia disperse through air and dust across cultivation, harvest, drying, trimming, and storage — often invisibly until it’s too late.
End-of-pipeline detection leaves no
options.
When contamination is found at state compliance testing, remediation is often impossible — and product disposal is the only path.
Early screening changes the outcome.
Our assay integrates into your workflow as an environmental and tissue monitor — identifying pressure before it escalates into batch loss.
• Validated molecular diagnostic
What is Aspergillus?
A simple swab-based workflow designed to fit into cultivation and post-harvest operations without disrupting your team.
A. fumigatus
Primary pathogen
Leading cause of invasive aspergillosis; airborne conidia are a primary inhalation hazard.
A. niger
mycotoxin risk
Common post-harvest contaminant; associated with ochratoxin.
A. flavus / A. parasiticus
mycotoxin risk
Major aflatoxin producers; potent carcinogens regulated across food and cannabis industries.
A. terreus
Antifungal Resistant
Resistant to amphotericin B; increasingly significant in immunocompromised patients.
• Method

01
Swab collection
Swab cannabis flower, plant tissue,
surfaces, or environmental sites like drying rooms, trim areas, and HVAC zones.
02
Fungal lysis & extraction
Proprietary extraction ensures
efficient fungal cell lysis. An internal control confirms sample integrity in every run.
03
Duplex TaqMan qPCR
Primer-probe sets simultaneously
target only the regulated species of Aspergillus, and nothing else.
04
Quantitative result
reporting
Results include a fungal load estimate and live/dead determination to enable targeted remediation before product advances to compliance testing.
•Technical validation
Inclusivity and Exclusivity Analysis
Every performance claim is backed by rigorous in-lab validation — limit of detection studies, 30-replicate species-specific studies, and blinded operator accuracy trials.
OVERALL ACCURACY
99.2%
Accuracy vs. Culture Plating
120 samples (90 positive, 30 negative) tested by a blinded, independent operator. Compared head-to-head against colony-forming unit confirmation via plating.
Low input (~3 CFU) 96.7%
Mid input (~25 CFU) 100%
High input (~100 CFU) 100%
False positives detected
(In a 30 sample study size)Not detected
LIMIT OF DETECTION
7.6 cells/rxn
Sensitivity across all four species
Determined across serial dilutions from 500,000 down to 2 copies per reaction (10 replicates each), then confirmed with 30 replicates at near-LoD concentrations per species.
A. niger LoD 15 copies (97%)
A. flavus LoD 7 copies (100%)
A. fumigatus LoD 7 copies (97%)
A. terreus LoD 15 copies (97%)
FIELD READINESS
48hr
Sample stability at ambient temperature
Accuracy validation samples were incubated at room temperature for 48 hours before testing — mirroring standard shipping times from customer facilities to the TUMI Genomics laboratory.
• Method
From swab to answer.
Cross-reactivity was evaluated via in silico BLAST
analysis against 253 microorganisms commonly associated with Cannabis sativa, Humulus lupulus
(hops), and the wider cultivation environment.
Only two organisms exceeded the 80% similarity
threshold for concern — and neither represents a
meaningful risk to cannabis safety testing.
A. oryzae — an industrial fermentation species, not found in grow facilities.
A. parasiticus — closely related to A. flavus; detection here is clinically meaningful, not a false positive.
• Inclusivity analysis
99.3%
of 1,524 known sequence variants showed 100% homology to primer/probe sequences.
100% of variants showed greater than 95% homology.
A. niger
213
sequences analyzed — 100% match
A. flavus
513
sequences analyzed — 98.8% at 100%
A. fumigatus
622
sequences analyzed — 99.7% at 100%
A. terreus
176
sequences analyzed — 99.4% at 100%
Primers and probes target highly conserved genomic regions. No analyzed variant
contained more than a single SNP within any individual primer or probe.
• Method
Built by scientists who've done it before.
Our lead scientists bring deep molecular biology expertise —
decades designing and validating in vitro assays, with specific
depth in cannabis pathogen diagnostics and remediation.
