More About Scanning

As eager as you may be to start testing with Oova, we want to be sure that we capture the data necessary to understand your body. More data is not always better.

Here is a list of topics covered on this page:

 

How does the Oova app know when I should scan a test?

Your first cycle of using Oova is very dependent on the information you enter upon registration. Our algorithm takes all of the information entered and determines which 15 days of your cycle you will need to use an Oova test. The goal here is to capture several days before your LH surge, your LH surge, and several days past your LH surge so we can capture your progesterone rise, assuming you had a successful ovulation.

For every subsequent cycle, we learn from the information captured in each previous cycle to determine when you need to use your Oova test. This means we may shift your 15-day scan window earlier or later based on our learnings.

Can I override my testing days?

If you would like to start testing sooner or later than the app is indicating, you can shift the scanning window accordingly. 

Go to Settings > My Cycle > My Scanning Window Offset and you can shift the days of scanning to be either earlier or later than it is currently set at. You can see the date that you will be able to begin scanning under the toggles. Once you Save your changes, the Scan Now button will appear on your home screen on the new start date.

If you are currently in an active cycle and would still like to continue testing, you will need to have the Oova team make some changes to your account. Please view details under What if I need to scan for more than 15 days?

How does scanning work? 

The home screen will indicate how many days until you should scan an Oova cartridge.

On a testing day, the home screen will change from showing you a countdown to a screen that says, "Scan Today" with a Scan Now button underneath.

Clicking on Scan Now will take you into the workflow to scan an Oova cartridge. You will be able to view a step-by-step tutorial or skip the tutorial and go straight to the timer.

At this point, you can provide a urine sample on an Oova cartridge. Take a new cartridge from the box and open it up. Be careful not to touch the tip of the sample pad to avoid contamination. Click the cartridge onto the holder.

You can either provide a sample midstream or as a dip test. If you provide the sample midstream, be sure to flip the cartridge upside down so the QR code points away from you and faces the toilet bowl. This is to avoid urine from splashing into the test line window.  Regardless of whether you provide the sample midstream or by dipping it into a cup of urine, apply the sample on the sample pad for 5-10 seconds. 

Once the sample has been applied, place the handle with the cartridge attached, on the holder. Start the timer on the app. It is very important that you wait the full 10 minutes before scanning the cartridge.

When the timer completes, you will be able to scan your Oova cartridge. Align the QR code and the test line window in the outlines provided on the screen. The cartridge should be either resting on the holder or lying flat on a surface. Avoid holding the cartridge in your hand as you try scanning.

Once the algorithm is able to capture a clean scan, you will be given the opportunity to approve the image that will be analyzed. If the test lines are clearly visible in the image, then approve the image for analysis. You will now be able to view the results (What do my results mean?).

Note: Do not scan an Oova cartridge after the 15 minute mark. After this, the results will not be accurate or representative of your hormone concentrations.

When should I test?

We recommend that you use your first morning urine, however, you should test at approximately the same time every day for the 15 days you will be using Oova in a particular cycle. For example, do not test in the morning one day, afternoon the next day, and evening the following day. The hormones being measured fluctuate throughout the day and we want to try to eliminate variables that could lead to inaccurate conclusions. 

If you wake up multiple times in the evening, we recommend that you don’t worry about Oova during your late night bathroom visits. Instead, wait until you wake up for the day and use that sample.

What if I need to scan for more than 15 days?

If you have an irregular cycle or unpredictable ovulation patterns, you may want to test for more than 15 days to monitor a larger portion of your menstrual cycle. Many clinicians using Oova with their patients request their patients to track their cycle for longer so they can get a good picture of the hormone patterns.

If you are not working with an Oova provider (i.e. you did not enter a valid clinic ID in your settings indicating that you are working with a clinician), you must contact our support team at support@oova.life to modify your permissions. This will allow you to scan outside of your scanning window and for a longer period of time.

If you are working with an Oova provider, your permissions have already been modified to allow you to this.

If you are in your scan window, you should continue to follow the steps indicated by the app to scan a cartridge each day. If you would like to scan an Oova cartridge outside of the 15 day scan window, go to Settings > My Details > Scan Now. By clicking on Scan Now, you will be able to scan an Oova cartridge outside of the scan window just as you previously did. 

Note: The home screen will remain unchanged.

Can I rescan an Oova cartridge?

You should refrain from scanning the same cartridge multiple times. By repeatedly scanning the same test cartridge, we are testing the limits of two things: a) the chemistry and b) the probability of an incorrect response. The chemistry is constantly running, even after the timer goes off so you will continue to see variability. We consider the 10 minute mark the ideal time to test and which is the moment we have based all of our accuracy measures on. By consistently rescanning, you are adding probability the test will return a bad result. 

If you feel the scan is inaccurate, then please take a picture of your cartridge and email our Support team at support@oova.life to analyze.

Tips for getting a good scan

  • When providing a urine sample midstream, flip the cartridge and handle upside down, facing the QR code away from you, to prevent splashing into the test line window.
  • Lay the cartridge either on the holder or on a flat surface during scanning to ensure a clean scan.
  • Scan your cartridge between the 10 minute and 15 minute mark. Any scans outside of this range are unreliable and will not be a good representation of your hormone levels.
