What is INDICA and when should presence/absence be used?
INDICA is the AquaVerify family oriented to presence/absence workflows and water microbiology screening. It is designed for routine checks, field, plant or laboratory teams that need a clear initial decision before escalating to enumeration, confirmation or further investigation. It can connect with AquaVerify Cloud to document sample, batch, result and action taken.
FAQ
Does INDICA provide a quantitative result?
INDICA should be positioned as a presence/absence or screening workflow, not as quantitative enumeration. If the user needs to compare loads, trends or concentrations, ENUMERA is usually more appropriate. The final decision depends on target organism, matrix and intended use.
When is INDICA useful in the field or plant?
INDICA can be useful when the team needs an operational decision on presence/absence, routine control or sample prioritization. The result should be interpreted within the internal procedure and, where relevant, complemented by confirmatory or enumeration methods.
Can INDICA be documented with AquaVerify Cloud?
Yes. AquaVerify Cloud can record sample, point, batch, operator, reading, result, evidence and related action. This helps maintain traceability and reporting, especially when screening is part of a broader control program.
Does INDICA replace accredited laboratory analysis?
It should not be presented as an automatic replacement. INDICA can support screening or routine control, but use for regulatory decisions depends on method, matrix, country, competent authority, laboratory and applicable scope.
When should a team escalate from INDICA to ENUMERA?
Escalation is useful when screening indicates presence, when microbiological load needs to be estimated, when root-cause investigation is required or when the control plan calls for quantitative evidence.
