Know your precise
delivery week.

How does the Arrival^TM Test work?  

Arrival looks at unique biomarkers, known as pregnancy clock proteins, along with personal health and lifestyle data to create a probability-based delivery prediction. By comparing your profile to millions of similar pregnancies, Arrival estimates the week you’re most likely to deliver. Biomarker analysis adds a personal layer of precision, which allows our prediction to account for your unique biology.

Why does it work?  

While a doctor gives a single estimated due date, only 5% of babies are born on that date.¹ Arrival Testing calculates a prediction of delivery range, reducing uncertainty and helping moms plan around the most likely week. With a strong clinical data foundation, Arrival offers greater confidence and preparedness for delivery timing, improving the overall pregnancy experience. 

How is Arrival Testing different than my Estimated Due Date (EDD)?  

The Arrival Test result is not a replacement for the Estimated Due Date that your provider has determined. Important milestones and care decisions are based on your provider’s EDD, and Arrival should not be used to influence those medical decisions. Information from the Arrival Test can help you plan for the most likely delivery week. In fact, your Estimated Due Date is required to complete the calculations used by the Arrival Test.  

I need customer support…how do I reach a live person? 
A live customer support representative can be reached from 7:00am to 6:00pm MT by simply calling 801-990-6600 or emailing support@arrival.health. 

I’m having twins, can I order Arrival?  

No. Regretfully, Sera does not have adequate data at this time to provide Arrival Test results for these pregnancies.

I conceived using fertility treatments, can I still order?

Unfortunately, no. Sera does not have adequate data at this time to provide Arrival Test results for these pregnancies. 

My doctor says my pregnancy is higher risk, can I still order? 

Yes. However, your doctor may make medical decisions for higher risk pregnancies that directly impact when you deliver. Some of those impacts are accounted for in the Arrival prediction, however there are many reasons for a pregnancy to be considered higher risk and not all are accounted for by Arrival testing. Arrival should not be used to influence medical decisions.

How do I track my Arrival kit? 

Once your Arrival Test order is processed, you will receive an email and text confirming your order. Soon after, you will receive a confirmation text that your kit has been shipped along with your tracking number.  

How will I know you received my Arrival kit? 

You will receive a text confirmation once we have received your collected sample.  

How does Arrival protect data?

To give you a safe and tailored experience, you are asked to agree to our Terms, Conditions and Privacy notice, prior to requesting your order. This helps safeguard your data and allows us to offer you personalized support through your ordering journey. Rest assured; we will never share your personal information.

What does it mean that you compare my personal data with other pregnancies?

Your Arrival Test results are personalized just for you. Measurements of specific protein levels in your blood are combined with your demographic and clinical information. Then, our proprietary Arrival algorithm finds pregnancies most like yours using millions of records to predict your baby’s most likely delivery week. 

How is my blood draw data used in the Arrival Test?

Your blood is analyzed to detect proteins that Sera has determined are highly associated with the timing of your delivery [Clock Protein Study]. This information is combined with your clinical and demographic data and then Sera’s proprietary Arrival algorithm predicts your baby’s most likely delivery week.  

How will I know when my results are ready? 
We’re excited to keep you in the loop every step of the way! Once your results are ready, you will receive a secure email. From there, you can easily view and download your results at your convenience.  

What if my health changes and my pregnancy becomes higher risk? 

If your health changes or you have new questions, you should contact your doctor. Your doctor may make medical decisions for higher risk pregnancies that directly impact when you deliver. Some of those impacts are accounted for in the Arrival prediction, however there are many reasons for a pregnancy to be considered higher risk and not all of them are accounted for by Arrival Testing.
