Is presence/absence less useful than enumeration?
No. It answers a different operational question. Presence/absence is useful for screening, while enumeration is useful when the concentration or trend matters.

Presence/absence vs enumeration in water microbiology
Understand when qualitative screening and quantitative enumeration workflows fit water microbiology decisions.
When presence/absence fits
Presence/absence workflows are useful when a team needs a clear qualitative answer for screening, release decisions or escalation.
- Fast yes/no decision points
- Operational monitoring where a qualitative answer is enough
- Field, quality or routine laboratory workflows
- Clear link to INDICA product families
When enumeration fits
Enumeration workflows are stronger when decisions depend on concentration, trend, limit comparison or quantitative reporting.
- Quantitative result records
- Trend monitoring across sites or batches
- Laboratory and customer reporting
- Clear link to ENUMERA and standard kits
Why the platform matters
AquaVerify Cloud can connect either workflow to sample context, operators, customer communication and CRM attribution.
FAQ
Can one organization use both workflows?
Yes. Many teams combine qualitative screening with quantitative confirmation or periodic enumeration depending on the sample type and decision.
