Upon project completion, our billing department will reach out to you with an invoice for services rendered.

Ensuring Data Quality

Using proper sample collection and storage techniques is critical to ensuring high-quality samples and data.

For collection and storage, we recommend DNA Genotek’s products​ as a gold standard for many types of samples. When possible, we also recommend that Diversigen carries out DNA extraction of your samples on site.

If extraction at Diversigen is not possible, we highly recommend following guidelines for submitting DNA found here​.

Microbiome measurements are susceptible to error, bias, and contamination at essentially every stage of the data generation process.

Incorporation of appropriate experimental controls is essential to ensure the reliability and reproducibility of microbiome data.

For every microbiome sequencing project, Diversigen includes both positive and negative controls on each DNA extraction plate as well as positive and negative controls on each library preparation plate.

These controls are carried through the full sequencing process and analyzed to ensure data quality.

Diversigen also provides an extensive​ QC Dashboard​ with each analysis report.

Each project is unique and at project completion you will receive a full explanation of the methods used to generate your data, including any relevant citations.

Diversigen’s services are based on optimized microbiome profiling methods described in peer-reviewed publications:

Sample Collection, Shipment, and Storage


Through Diversigen’s sister company, ​DNA Genotek​, we offer OMNIgene® collection kits for oral, gut (stool/fecal), skin and vaginal microbiome.

These optimized and validated collection solutions provide ambient temperature stabilization at the point-of-collection for a true snapshot of the microbiota with no cold chain required.

Learn more about these collection kits and request trial kits.

If you have questions about collecting other types of microbiome samples, ​contact DNA Genotek.

Diversigen stores primary samples at our facility for up to three months and is happy to return samples to clients after processing.

Please notify Diversigen before sample submission, if you are planning on having your samples returned, to provide shipping and payment information for return of samples.

Yes, Diversigen will archive the data for your project for one year with no additional charge.

Yes! Although Diversigen is located in the United States, we are happy to accept samples from around the world.

Working with our preferred international shipper, World Courier, will make the transportation of your samples simple and efficient. In our experience, only a non-hazardous declaration is required for human samples that are not known to, or suspected of, containing an infectious biological agent.

The declaration must include:

  • A detailed description of the material
  • A statement on official letter head signed by the person responsible for the shipment clearly stating that (1) the material is not known or suspected to contain an infectious biological agent and (2) how the person making the certification knows that the specimen does not contain an infectious biological agent; or the basis of the belief that there is no reason to suspect that the specimen does not contain an infectious biological agent; or a detailed description of how the material was rendered non-infectious.

For non-human samples (including soil, animal and agricultural) or human samples that may contain an infectious biological agent, please reach out to your Diversigen representative for detailed information on shipping.


Diversigen has experience working with a wide range of sample types, including human gut (fecal), vaginal, urine, skin, oral, saliva, and biopsy samples, as well as in vitro cultures, animal, plant, soil, built environment, and other environmental samples.

We have worked with a variety of collection formats including bulk samples, swabs, and samples collected in stabilization buffers or directly frozen.

If you have questions about whether your sample type is suitable for analysis or which collection method to use, please ​contact us​.
