Overview
Use this FAQ to select the appropriate sampling method, understand turnaround times, prepare samples correctly, review report indicators and learn about important laboratory procedures.
Top FAQ
Which sampling method is better: vacuum cone or Swiffer cloth?
The Swiffer method is preferred for most whole-home or whole-office dust collection. Dust should be collected from multiple representative areas, including cabinet tops, door frames, window sills, ceiling fans, shelves, dressers, nightstands and HVAC return vents.
The cloth should visibly contain dust. Vacuum cones are useful for collecting dust from a defined 22-square-foot carpeted area. The cone connects to the vacuum hose, and the inner tube should contain as much dust as possible.
What do the turnaround options mean?
Turnaround time, often abbreviated as TAT, refers to the laboratory processing time after a sample is received and begins analysis.
Each option may have a different cost. Turnaround times are calculated in business days and do not include weekends, holidays or shipping time.
How do I receive my results?
Results are emailed to the address listed on the Chain of Custody form.
Your confirmation email includes the reference number used to track each submitted sample.
How should I interpret my results?
EnviroBiomics can provide general report guidance. Results should be reviewed in context with your Indoor Environmental Professional or qualified healthcare provider.
Reports may include reference values, calculated scores and indicators showing how reported values compare with available reference information.
Dry Swiffer collection method

Where to collect

Just enough dust for one test.
Plenty of dust for one test.
Enough dust for more than one test.
Tips for reading reports
Report values should be reviewed in context with the sample type, building history, inspection findings and appropriate professional guidance.
| Topic | Report guidance |
|---|---|
| Color-code labels | Review the report legend carefully. Colors and asterisks may indicate how reported values compare with reference or average values. |
| Mycotoxin report | Mycotoxin reports may use Q-level classifications rather than the fold-change format used in some other reports. |
| Q-level summary | Q levels organize reported results by their position within available reference distributions. |
| Score analysis | Scores are calculated values and should be reviewed together with reported organisms, reference values and other report indicators. |
| Reference data | Available reference data may vary by test, organism, building characteristics and the reference population used. |
| Professional guidance | Building-related questions should be reviewed with an Indoor Environmental Professional. Medical questions should be discussed with a qualified healthcare provider. |
| MSQPCR format | MSQPCR-format reports may provide organism and quantity data without including a calculated environmental score. |
