< RL = below the laboratory reporting limit (compound not detected at or above the listed limit). A "Not Detected" result indicates the compound was below the reporting limit, not that it is necessarily absent. Concentrations are reported in picograms per square centimeter (pg/cm²) normalized to the 100 cm² sampled area. All 40 analytes determined by LC-MS/MS.
Ochratoxin A is a mycotoxin produced primarily by certain species of Aspergillus (notably A. ochraceus and A. carbonarius) and Penicillium (notably P. verrucosum). In the built environment it is most often associated with materials that have a history of moisture intrusion or water damage.
The concentration measured here (1.4 pg/cm²) is low, but it is above the laboratory reporting limit and therefore reported as a confirmed detection. Its presence on the HVAC return register suggests a localized source worth investigating.

Interpretation & Recommendations
A single mycotoxin, Ochratoxin A, was detected at a low concentration of 1.4 pg/cm². Ochratoxin A is produced by certain Aspergillus and Penicillium species and is frequently associated with previously water-damaged building materials.
Importantly, the macrocyclic trichothecenes — the Stachybotrys-associated toxins that are often of greatest concern — and the aflatoxins were not detected. That is a meaningfully reassuring finding for this sample. The result you see here is a low, single-compound detection consistent with a localized source rather than widespread amplification.
A word on what this measurement does and does not tell us: results pertain only to the specific surface that was sampled — the HVAC return register. A "not detected" result means the compound was below the laboratory reporting limit on that surface, not that it is necessarily absent elsewhere in the home. With that context, here is what I would recommend.
-
Investigate the HVAC system and adjacent materials.Look for evidence of past moisture or condensation around the return — staining, prior leaks, or insulation that has been damp — which could indicate an Ochratoxin-producing mold source feeding the register.
-
Pair this panel with a mold assessment.An ERMI analysis or direct sampling will help localize and characterize any growth, putting this single detection in the broader context of the home's microbial profile.
-
Clean or remediate any source, then re-sample to confirm.Address any identified source per industry guidance, and re-test the same surface afterward to verify the detection has cleared.
About This Test
Analytical Method
Liquid chromatography–tandem mass spectrometry (LC-MS/MS). The surface wipe extract is separated by liquid chromatography and each compound is identified and quantified by its characteristic mass transitions — a highly specific and sensitive technique for trace-level mycotoxin analysis.
What This Test Shows
A targeted screen for 40 mycotoxins across five toxin classes on the sampled surface. It reports whether each compound is present above its reporting limit and, where detected, at what concentration normalized to the 100 cm² wipe area.
What It Does Not Show
This panel does not identify the mold species producing a toxin, locate hidden growth, or characterize airborne spore levels. It reflects only the surface sampled at the time of collection. Pair with a mold assessment for a fuller picture.
On "Not Detected"
A result of "Not Detected" means the compound was below the laboratory reporting limit for this sample. It should not be read as an absolute zero or as confirmation that the compound is absent from the home.
