Urine Microbiome

Understand the microbial ecosystem of low-biomass urinary samples

While urine was traditionally assumed to be sterile, advanced sequencing reveals complex microbial populations that play critical roles in urological health, systemic conditions, and infectious diseases. Because urine is inherently low-biomass and low-diversity, our specialized workflows are engineered to minimize contamination and accurately capture these delicate microbial signatures.

Low-Biomass Optimization: Special handling protocols designed specifically for low-density, low-diversity samples
Laminar Flow Processing: Strict cross-contamination mitigation strategies to preserve sample integrity
Total Quantification: qPCR bacterial quantification to gauge initial amplification and content
Advanced Bioinformatics: Tailored bioinformatic pipelines with a deep understanding of low-biomass data analysis

Every Urinary Study, Analyzed with Confidence

From careful sample collection through advanced bioinformatics interpretation, our team delivers optimized workflows to handle the technical challenges of low-biomass urinary specimens.

Healthy Cohort Profiling

Establishing baseline urobiome standards and identifying low-abundance commensal populations in healthy individuals to understand the normal, non-pathogenic urinary baseline.

Urological & Pathogenic Research

Investigating dysbiosis and specific microbial pathogens associated with major bladder and prostate conditions, including UTIs, overactive bladder (OAB), interstitial cystitis, and prostate health.

Systemic Disease & Biomarker Discovery

Exploring the complex gut-bladder axis and systemic links between the urinary microbiome and wider metabolic diseases, oncology, and immune system health.

Low-Biomass Optimization Studies

Specialized processing designed to maximize DNA extraction and improve sequencing yields from highly dilute, low-biomass, and low-diversity urine environments without sacrificing sample integrity.

Contamination-Controlled Studies

Implementing strict laminar flow processing and sampling strategies (such as midstream collection tracking) to cleanly differentiate true urinary microbes from surrounding vaginal or skin cross-contamination.

Longitudinal Clinical Trials

Utilizing standardized sampling protocols and advanced preservation methods (like Norgen Biotek solutions) to monitor stable, room-temperature urobiome shifts during therapeutic or dietary interventions.

Protocol

Urine samples are extracted using the Macherey-Nagel NucleoMag DNA Microbiome Kit , optimized for high-throughput extraction using the ThermoFisher KingFisher automated robot. A robust bead-beating step is integrated into the protocol to ensure full lysis of resilient microorganisms.

To combat the challenges of low biomass, we optimize the amount of starting material used to improve sequencing yields. Crucially, all samples are processed under a bio safety cabinet to eliminate external environmental contaminants and ensure absolute data integrity.

Choosing the Right Collection Method for Your Study

Because urine is highly susceptible to external contamination and degradation, immediate stabilization is vital. We highly recommend stabilizing specimens at the point of collection to preserve the baseline microbial snapshot.

Collection Method	Recommended Kits	Storage & Shipping
Preserved Liquid Method (Highly Recommended)	Norgen Biotek Urine Preservation Solution (Single-dose ampule or dried format)	Store at room temperature. Ship at room temperature (no dry ice required).
Standard Sterile Method (Unstabilized)	Standard Sterile Urine Cup	Requires immediate freezing at -80°C. Must be shipped on dry ice.

100% Private & Discreet: We use blank packaging, never collect direct identifiers (like patient names), and store personal information entirely separate from your sample.

Collection Instructions

Preserved Liquid Method

Step 1: Collect midstream urine in a sterile container. First-flow urine is not recommended. Note: Cleaning the external area prior to collection is highly recommended to prevent vaginal or skin microbe contamination.
Step 2: Add the required amount of midstream urine (depending on the specific volume protocol you are following: 1–5mL, 15mL, or 50mL) to the Urine Collection and Preservation Tube containing the Norgen Biotek preservation solution.
Step 3: Once the urine has been added, tightly secure the orange cap back onto the tube to seal it completely.
Step 4: Fill out the required sample ID information on the provided label, affix it to the tube, and store at room temperature until ready to ship.

Questions About Urine Microbiome Sequencing

How should I collect urine microbiome samples?

We recommend a clean-catch, midstream urine collection into a sterile container to minimize external contamination from skin or vaginal microbes. For optimal stabilization, the sample should be transferred immediately into a collection tube containing Norgen Biotek Urine Preservation Solution.

Why is urine considered a challenging sample type?

Urine is a low-biomass and low-diversity sample matrix. This means it contains very few microbes compared to environments like the gut. Because the microbial DNA signal is faint, these samples require specialized extraction protocols and sterile, laminar-flow processing environments to prevent environmental contamination from skewing results.

Can you detect antimicrobial resistance (AMR) genes in urine?

Yes. Using shotgun metagenomic sequencing, we can profile the functional genetic potential of the urinary microbiome, which includes identifying the presence and abundance of antimicrobial resistance (AMR) genes.

How long does urine microbiome sequencing take?

Most projects are completed within approximately 6 weeks. This timeline depends on total sample volume, the specific sequencing approach chosen, and any specialized low-biomass bioinformatic filtering required.
