Frequently Asked Questions

These frequently asked questions (FAQ) are designed to help you have the best possible research experience.  Feel free to contact us with any questions or concerns by email at [email protected] or by phone at YouCanBook.Me.

What is the Purpose of this study?

MetricBio is conducting a research study to look at glyphosate levels in the urine of participants and investigate overall exposure to the chemical in different US regions.  Glyphosate is a chemical used to kill grasses and other plants and is found in many commonly used herbicides (weed killers). Little is known about human exposure and uptake of the chemical. Currently, only US residents are sought for enrollment in this study.

If you participate in this study you will receive access to your personalized research report that will include the concentration of glyphosate in your urine sample. Your research data will be 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.

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 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.

All results are for educational and research purposes only. We will not return any clinical or medical information to you.  Although our procedures are highly accurate, our laboratory is not a clinical or medical diagnostic laboratory.

Does this research meet regulatory requirements?

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 if the research should be done and advocates for the safety and well being of study participants.

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

Study participants are required to first register at www.metricbio.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 need to partially cover the cost of the analytical test.

Registration will require you to provide some basic information such as your mailing address (postal address), email address, and your phone number.  All payments will be processed using PayPal; please refer to their website for further details.  It is not necessary to have a PayPal account to participate in the study or to submit payments through PayPal.

If you consent to participate in our study, we will ask you basic personal information including date of birth, gender, height and weight.  You will also have the opportunity to participate in a detailed 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 medically 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 the urine sample that you submitted.

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.  If you decline to allow biobanking of your sample, this will not affect the analysis of your urine glyphosate concentration, and any remaining urine will be discarded after we report your results to you.

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 business days please contact the study coordinator at [email protected]

What should be 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 pre-paid 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?

If you did not receive your research kit within 10 business days of enrolling in the research or if your kit arrives damaged or missing contents, please contact us at [email protected].

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, it is best to ship your sample immediately. Samples should be mailed within 3 days of collection. If your sample is not shipped within three days of collection, please email us at [email protected] before shipping the sample so we can determine if you should collect a fresh sample.

How do I collect my sample?

Step-by-step instructions are included in the research kit.  These instructions are also available at www.metricbio.org/step-by-step/

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

No, all supplies and postage necessary to send your sample for analysis and inclusion in this research are provided in your research kit.

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.

What kind of results will I get?

After your sample has been analyzed, we will report the level of glyphosate found in your urine sample. Once enough participants’ samples have  entered the study, we will apply statistical tests to calculate population averages by region and across the US, and compute whether or not differences are statistically significant. . These averages will continuously be updated as additional samples are analyzed.

In the future, we plan to develop tools for the website portal enabling you to display and explore the aggregate data in various ways (for instance males vs. females, U.S. state vs. U.S. state).

All results are for educational and research purposes only. We will not return any clinical or medical information to you. Although our procedures are highly accurate, our laboratory is not a clinical or medical diagnostic laboratory.

Do you ship outside the United States?

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

Can my children be part of this research?

No, currently this research project is set up only for adults (18 years or older). We may add children to this research in the future. If you would like to express interest in your children participating 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 must provide consent.  Therefore, you may not purchase a research kit for someone else. Please provide this link to parties interested in participating (www.metricbio.org).

How do I change my password, 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]

Can I order multiple research kits for myself?

Yes, however our current portal does not allow ordering of multiple research kits simultaneously. It will only allow you to order an additional research test after your prior results have been reported back to you.
