What is the Purpose of this study?

MetricBio is conducting a research study to measure glyphosate levels in urine of participants and investigate overall exposure to the chemical by U.S. region. Glyphosate is a chemical used to kill weeds and other plants and is found in many commonly used weed killers. Little is known about human exposure and uptake of the chemical. Currently, only United States residents are sought for enrollment into this study.

As a study participant, you will be provided access to your personalized research report, which will include the concentration of glyphosate in your urine. Your research data will be made available to you through our website at www.metricbio.org.

All results are for educational and research purposes only. We will not return any clinical or medical information to you. The testing we use is not appropriate for clinical use or medical diagnosis.

What will be expected of me as a research study participant?

Study participants are required to first register at www.metribio.org, then to review and formally agree to participate in the study through a process called informed consent.

To participate in this study you will be required to cover the cost of the analytical test, including the collection and analysis of your urine sample. Currently, only PayPal payments are accepted.

Registration will require you to provide some basic information such as your mailing address (postal address), email address, and your phone number. Payments will be processed using PayPal, please refer to their website for further details on how to set up your PayPal account.

If you consent to participate in our study, we will ask you to share basic personal information including date of birth, gender, height, and weight. You will also have the opportunity to participate in an advanced questionnaire related to potential sources of glyphosate exposure. These questions include habitual diet, outdoor activities, general features of the area in which you reside and your use of glyphosate related chemicals. We will not ask any health or medical related questions. You may decline to answer any of these additional questions.

We will provide a urine collection container and instructions for shipment. You will be asked to collect your urine using the provided container and ship it to the MetricBio laboratory for analysis. Once analysis is completed you will receive a report of the glyphosate concentration in your submitted urine sample.

When enrolling in the research study you will be asked if you wish to allow your urine sample to be retained by MetricBio (biobanked) for use in future research studies, which may or may not be related to glyphosate. Declining to allow biobanking of your sample will not affect the analysis of your urine glyphosate concentration, and any remaining urine from you will be discarded after we report your results to you.

Where is this research being done?

U.S.-based MetricBio LLC. is conducting the research in a modern, state-of-the-art laboratory. The laboratory is staffed with researchers with a strong background in analytical chemistry and biochemistry.

What testing method is used to test my sample?

This research will use liquid chromatography coupled to mass spectrometry (LC-MS/MS) to measure the absolute concentration of glyphosate in your urine. Each test sequence includes calibration curves and quality control samples to assess reproducibility and quality of measurements. We use internal standards composed of isotopically labeled glyphosate to match each measurement against the compound of interest.

Do you ship outside the United States?

No. This research project is set up for residents of the United States. If you reside outside of the United States and would like to take part in this study, please send us an email at [email protected] to let us know of your interest.  We will let you know as soon as we are able to expand this study beyond the U.S.

Can my children be part of this research?

No. Currently we are only enrolling adults (18 years or older). However, we may include children in this study in the future. If you would like to express interest in having your children participate in the research, please email us at [email protected].

Can I purchase a kit for someone else?

No. This is a research study for which you will be required to provide consent. As a result, you may not purchase a research kit for someone else. Please provide this link to interested parties (www.metricbio.org).

Does this research meet regulatory requirements?

Yes. Our research is IRB approved by the Western Institutional Review Board (WIRB). An IRB (Institutional Review Board) is an ethics committee that reviews and monitors research projects that involve human subjects. The IRB determines whether the research should be conducted and advocates for the safety and well being of study participants.

When can I expect to receive my kit?

Standard shipping is used for kit delivery; your kit should arrive within 5-10 business days. If you have not received your kit after 10 days please contact the study coordinator at [email protected].

When will I get my results?

We will start processing your sample as soon as it is received. The standard turnaround time from sample receipt to final report is typically 4-6  weeks.

How do I update my email address, home address or other information?

You may reset your password by clicking the “Profile” tab on the website and selecting the “Account Details” button. You can update your mailing address by clicking the “Profile” tab and selecting “Manage your addresses”.  If you need assistance with updating your information please send us an email at [email protected] and we will help you with the update.

How long will my research kit last?

Research kits can be stored at room temperature until you are ready to collect your sample. Once you’ve collected your urine sample, we recommend that you ship your sample immediately. Samples should be mailed within three days of collection. If your sample is not shipped within three days of collection, please email us at [email protected] before shipping so we can determine if you should collect a fresh sample.

Do I need to pay for postage to send my sample?

No, all supplies and postage necessary to send your sample for analysis are provided in your research kit. The research kit includes a mailing envelope with a pre-paid shipping label to send your sample to the MetricBio laboratory.

How do I collect my sample?

Step-By-Step Instructions are included in the research kit. The same instructions are also available on www.metricbio.org/step-by-step/.

What is included in my research kit?

Each research kit should contain: 1 cardboard box, 1 zip lock bag (with a small absorbent sheet that MUST remain in the bag in case of leaks), 1 urine collection cup, a return envelope with a return shipping label, and instructions on how to collect your sample. After the sample is collected, place the cup in the bag provided, seal the bag and place it in the box before shipping in the pre-paid envelope.

My research kit was lost or damaged, what do I do?

Once we receive your order, we will assemble your research kit and ship it to you in a timely fashion (5-10 business days). In the unlikely event that you receive a confirmation of delivery, but the kit was not delivered, please contact us at [email protected].

If your research kit was damaged during shipment or is incomplete, please contact us at [email protected].

What kind of results will I get?

After your sample has been analyzed, we will report to you the concentration of glyphosate measured in your urine sample. Once enough participants have been accrued into the study, we will apply statistical tests  to calculate population averages by region and across the U.S., and compute whether differences are statistically significant. These calculations will be continuously updated as additional samples are analyzed.

In the future, we plan to introduce new features to the MetricBio portal, which will allow you to display, query and explore the aggregate data in various ways (for instance exposure in woman vs. man, comparison by U.S. state).

All results are for educational and research purposes only. We will not return any clinical or medical information to you, and the testing we use is not appropriate for clinical use or medical diagnosis.
