RealTime Laboratories Review: Mycotoxin Urine Test

What is RealTime Laboratories

RealTime Laboratories is a clinical laboratory based in Texas that sells urine and environmental panels. The company states that its urine panel measures selected mycotoxins and that its laboratory is CLIA certified and CAP accredited. Those credentials address laboratory operations; they do not establish clinical validity for a mold-related diagnosis.

RealTime states that the urine panel is sold directly to consumers and can be collected at home. Direct availability does not make the result diagnostic. The panel reports compounds in urine, not conditions in a building, and cannot identify a source, prove illness or causation, or establish whether a space is safe.

Company-described collection process

The company describes the following product process. These are collection and reporting facts, not medical guidance.

• Kit delivery. RealTime states that it ships collection materials, instructions, and a prepaid return label within the continental United States.
• Collect a urine sample at home. Use only the included kit directions. We do not recommend supplements, binders, sweating, or other attempts to alter a sample. CDC states urine mycotoxin tests are not FDA-approved for clinical use, so altered collection does not make a result diagnostic.
• Return shipping. The company directs customers to seal and return the sample with the provided materials.
• The lab runs a competitive ELISA. ELISA stands for enzyme-linked immunosorbent assay. It uses antibodies made to bind specific mycotoxins. RealTime reports this method as analytically validated for accuracy, precision, sensitivity, specificity, and reportable range under CLIA and CAP standards.
• You get a report. Results come back in roughly 7 to 10 business days. Each of the 16 mycotoxins is reported with a measured value in parts per billion (also written as nanograms per milliliter), so you see a number for each toxin rather than a simple pass or fail.

The parts-per-billion report is a laboratory measurement, not a clinical conclusion. CDC notes that mycotoxins can appear in urine from dietary exposure and that levels predicting disease have not been established. Do not use a result to infer a source, illness, or a need for a detox protocol.

What it tests for and what you get

The headline number is 16 mycotoxins, and the panel is unusually broad because it includes nine macrocyclic trichothecenes, the group linked to Stachybotrys, the mold many people call black mold. Here is the full list RealTime reports on its Mycotoxin Panel.

RealTime says the product includes a collection kit, prepaid return materials, and a report listing each analyte and measured level. The company also lists broader urine and environmental products at separate prices. An environmental dust product measures a different sample, and EPA does not recommend ERMI for routine consumer use. Neither product type establishes illness, causation, source location, clearance, or safe occupancy.

Pricing and what is included

RealTime lists the core Mycotoxin Panel at about $399, while some practitioner portals list prices closer to $299. The company also lists broader and environmental panels at higher prices. Prices and terms can change.

• RealTime states that the panel is HSA and FSA eligible.
• The company says insurance or Medicare coverage may require a physician order and varies by plan.
• RealTime does not list a separate draw fee for the at-home urine kit.
• The company says prepaid return shipping is included within the continental United States.

Price and payment treatment do not establish clinical validity. A urine panel and a building investigation are not substitutes.

Laboratory operations and clinical validity

What the company reports

RealTime states that its laboratory is CLIA certified and CAP accredited and that the assay is analytically validated for defined laboratory characteristics. Those claims describe how a target compound is measured under the laboratory method. They do not establish that the result predicts disease, identifies a source, or supports a treatment or occupancy decision.

The clinical meaning is contested

CDC states that urine mycotoxin tests are not FDA-approved for clinical use and that disease-predictive levels have not been established. Mycotoxins can appear in urine after dietary exposure, including in healthy people. A result is not diagnostic. It does not establish that a building caused symptoms, identify a source, or determine what medical or environmental action is appropriate.

Collection changes do not solve the validity problem

We do not recommend altering collection conditions. A manufacturer’s collection instructions describe its product process, but CDC states urine mycotoxin tests are not FDA-approved for clinical use and do not have established disease-predictive ranges.

Company-reported product facts

• RealTime states that its laboratory is CLIA certified and CAP accredited.
• The company lists 16 analytes and describes a competitive ELISA method.
• The company describes at-home urine collection and a turnaround of about 7 to 10 business days after receipt.
• RealTime states that the direct-to-consumer panel is HSA and FSA eligible; insurance and Medicare coverage may require a physician order and varies by plan.

None of these product facts establishes clinical validity. The result is not diagnostic and does not establish causation, locate mold, or establish clearance or safe occupancy.

Evidence and decision limits

• It measures your body, not your building. This is the big one. A urine panel cannot tell you whether mold is growing in your home or where. It is the wrong tool if your goal is to find a source.
• Not recognized for diagnosis. The CDC and FDA do not endorse urine mycotoxin testing as a validated diagnostic, and it is not FDA cleared for that use.
• No established disease-predictive levels. A measured number cannot be converted into a diagnosis or personal health threshold.
• Diet drives positives. A large share of healthy people test positive from food alone, so a positive does not prove a building problem.
• Hard to interpret without expertise. With no standard reference ranges, a parts-per-billion number is difficult for a layperson to act on, and two labs can produce different-looking results for the same person.
• The method is debated. RealTime uses competitive ELISA, while some competitors use mass spectrometry (LC-MS/MS) that critics consider more specific for these trace levels. No independent standard settles which is better.
• Cost adds up. At roughly $399, and often paired with practitioner visits or a separate environmental test, the total spend can climb quickly.
• No treatment or occupancy conclusion. The result does not establish a treatment need, remediation scope, clearance, or safe occupancy.

What the result cannot decide

This panel is not a suitable basis for a diagnosis, causal conclusion, treatment decision, remediation scope, clearance, or occupancy decision. It does not answer whether mold is present in a building or where a moisture source is located. Building questions require a qualified building investigation, and health concerns require evaluation under established medical guidance.

How it compares to alternatives

Versus other urine mycotoxin labs

RealTime describes competitive ELISA, while several competing laboratories describe mass-spectrometry methods. Panels, methods, and laboratory ranges differ, and no result from this testing category is recognized by CDC or FDA as a validated diagnosis of mold-related illness.

Versus DIY mold test kits

A hardware-store mold plate or a DIY mold testing kit samples a limited location or material from a building, while RealTime samples urine. Settling plates and other limited DIY samples cannot establish a complete source, remediation scope, clearance, or safe occupancy.

Versus environmental dust testing (ERMI)

An ERMI test applies a research index to mold-DNA measurements from settled dust. EPA does not recommend ERMI for routine consumer use. A urine panel and a dust index measure different samples, and neither establishes illness, causation, source location, clearance, or safe occupancy.

Versus a professional inspection

A qualified building professional can investigate building history, moisture, accessible materials, and any defined sampling question. A urine result cannot perform that work. See the limits described in our guide on how to test for mold.

Collection facts and limits

RealTime publishes collection, packaging, and return instructions with its kit. Follow only the current manufacturer directions for handling a purchased product. This review does not recommend buying the panel or modifying collection conditions. Do not treat a result as a diagnosis or use it to establish causation, a building source, treatment, clearance, or occupancy.

Evidence-based conclusion

RealTime publishes laboratory credentials, a defined analyte list, a collection process, and a reporting timeframe. Those product facts do not establish clinical validity. CDC states that urine mycotoxin tests are not FDA-approved for clinical use and that levels predicting disease have not been established. Do not use this panel as a diagnosis. It does not establish causation, a building source, treatment, clearance, or safe occupancy.

Screen visible surfaces with Mold Scanner AI

A urine panel and a building investigation answer different questions. Mold Scanner AI guides visible-surface photo capture and provides AI-assisted visual screening with variable processing time. It cannot locate hidden growth, trace a source, choose sampling sites, or determine whether a health test is warranted. Use a qualified inspector, laboratory, and clinician as appropriate.
