Stool Sample Tips to Improve Accuracy: Insights from Viome, Zoe & InnerBuddies Users

Accurate stool sample collection is fundamental to reliable microbiome testing. Sample integrity depends on avoiding contamination and degradation from collection through transit. This article summarizes practical, evidence-based practices recommended by Viome, Zoe, and InnerBuddies users and explains why small steps—timing, storage, and handling—matter for meaningful gut microbiome results.

A good stool sample should represent your typical gut microbiota. Contamination with toilet water, skin contact, or exposure to oxygen can alter microbial composition and DNA quality. Similarly, delayed processing or exposure to heat accelerates microbial shifts and decomposition. Following a standardized procedure reduces variability and improves comparability across tests.

• Maintain your usual diet for several days before sampling; avoid abrupt dietary changes.
• Do not take antibiotics, probiotics, or heavy-dose supplements in the days immediately prior unless your testing instructions say otherwise.
• Collect in the morning when possible to limit diurnal variation in stool composition.

These steps help ensure the sample reflects your typical gut ecology rather than a temporary perturbation.

Viome uses a specialized stool cap that seals and stabilizes the sample rapidly to limit oxygen exposure, which can favor or suppress certain taxa. Users report that securing the cap without touching internal surfaces reduces contamination risk.

Zoe emphasizes temperature control: immediate refrigeration when same-day shipment is not possible and insulated packaging with cooling elements during transit. Cold storage slows microbial growth and metabolic activity that can shift community structure.

InnerBuddies supplies compact kits with clear instructions designed for quick, clean collection. Common user advice includes preparing a clean collection surface, wearing gloves, and sealing the sample promptly after obtaining it.

• Use only the tools provided in the kit; avoid using household containers.
• Prevent contact with toilet water—collect on a clean surface or collection paper.
• Avoid touching the sample with bare hands and seal the container immediately.
• Label the sample clearly and store it as instructed (refrigerate if indicated).

Combining rapid sealing (Viome-style) with temperature control (Zoe-style) and simple, clear procedures (InnerBuddies-style) captures the strengths of each approach and reduces common errors.

Follow carrier and laboratory instructions for packaging and shipping. Tracking the package helps ensure timely delivery; prolonged transit at ambient temperatures can affect results. Once the lab receives the sample, DNA extraction and sequencing begin—small pre-analytic differences can influence downstream interpretation, so consistency matters.

Careful preparation, hygienic collection, rapid sealing, and appropriate temperature control are the core practices that improve stool sample accuracy. Following clear instructions and minimizing pre-analytic variation increases the likelihood that lab results will reflect your true gut microbiota composition.
