Hospital-grade clinical laboratory accuracy for your home or commercial property. Directed by a board-certified Medical Laboratory Scientist (MLS(ASCP)CM #25407471), our state-accredited Texas City laboratory (TDLR LAB #1050) operating under AIHA LAP, LLC accreditation standards (EMLAP) and ISO/IEC 17025 standard analyzes air cassettes, surface swabs, and water samples locally—eliminating out-of-state shipping delays and giving you clear, trustworthy results in 24 hours or less.
AIHA LAP, LLC EMLAP ACCREDITED • ISO/IEC 17025 STANDARD • ASCP CLINICAL OVERSIGHT • ZERO SHIPPING DELAYS
Most inspection companies mail your air and surface samples out of state in hot cargo trucks, risking sample degradation and delaying your answers by 3 to 5 days. Envirogyn analyzes all samples right here in Texas City under board-certified clinical laboratory leadership.
CLINICAL MICROBIOLOGY
AIHA EMLAP • ASCP MLS #25407471
Environmental Microbiology Laboratory (EMLAP)
Hospital-grade clinical pathology standards applied to environmental testing. Directed by a board-certified Medical Laboratory Scientist (ASCP MLS #25407471) with ISO/IEC 17025 quality management.
Medical Scientist Oversight: Direct evaluation by a credentialed clinical pathologist rather than high-volume assembly-line readers.
Local Bench Processing: Hand-delivered to our Texas City lab so samples never bake in 100°F freight trucks.
Comprehensive Testing: Airborne spore traps, viable mold cultures, bacteria (E. coli / coliforms), and drinking water analysis.
Court-Admissible Reports: Easy-to-read, legally defensible Certificates of Analysis for homeowners, doctors, and insurers.
State-licensed mold testing facility operating under TDLR LAB #1050. We perform ASTM D7391 spore trap air counts, ASTM D7658 surface tape-lift exams, bulk material testing, and home test kit analysis.
100% Full-Slide Trace Scans: High-magnification 400x/1000x oil-immersion microscopy so toxic mold genera like Stachybotrys are never missed.
Clear Indoor vs. Outdoor Comparison: Quantitative spores/m³ compared against outdoor baseline air to confirm if indoor air is healthy.
Surface Swabs & Tape Lifts: Identifying whether visible spots are active mold growth or harmless household dust/soot.
Open to Consultants & Homeowners: Accepting samples from independent Texas inspectors and mail-in home test kits.
Standardized Mold Air & Surface Diagnostic Services
Bench analysis conducted in strict compliance with ASTM standard test methods under AIHA LAP, LLC EMLAP accreditation guidelines and ISO/IEC 17025 quality management. Available with STAT 3-hr, Same-day rush, or Standard 24-hr turnaround.
BIOAEROSOL ANALYSIS
ASTM D7391-20 • SPORE TRAP ANALYSIS
Mold Air Test (Spore Trap Optical Microscopy)
Volumetric bioaerosol air testing utilizing calibrated inertial impaction cassettes (Air-O-Cell, Allergenco-D, Z5) at 15.0 L/min. Evaluates airborne spore loads, fungal ecology, and indoor vs. outdoor concentration ratios.
Methodology: ASTM D7391-20 optical compound microscopy at 400x/1000x with 100% full transverse trace scan.
Quantitative Metrics: Raw counts, volume calculations, and quantitative concentrations in spores per cubic meter (spores/m³).
Turnaround SLAs: STAT 3-hr emergency processing, Same-day rush (12-hr), and Standard 24-hr delivery.
Accreditation: Analyzed under AIHA LAP, LLC EMLAP and ISO/IEC 17025 standard operating procedures.
Mold Surface Test (Direct Microscopic Examination)
Direct Microscopic Examination (DME) of surface tape-lifts, sterile swabs, and bulk building materials. Differentiates active fungal colonization with conidiophores and hyphae from harmless settled particulate dust.
Methodology: ASTM D7658-17 Direct Microscopic Examination (DME) on specialized optical adhesive Bio-Tape slides.
Biomass Rating: Semi-quantitative colonization scale (None Detected 0 to Heavy Mycelial Mat 4+).
Turnaround SLAs: STAT 3-hr emergency processing, Same-day rush (12-hr), and Standard 24-hr delivery.
Clinical Accuracy: ASCP board-certified Medical Laboratory Scientist differential taxonomic analysis.
