How can a COVID-19 Antibody Test help you?

The antibody test can show you:
  • If your antibody levels are high enough to help protect your body from severe symptoms*.
  • If it’s likely you’ve had a COVID-19 infection in the past.
  • How your antibody levels declined over time.
*These antibodies are a marker of your protection against COVID-19, but they do not guarantee that you are immune to getting COVID-19.
*Antibodies are a marker of your protection against COVID-19, but they do not guarantee that you are immune to getting COVID-19.

Your COVID-19 antibodies decline over time

The test measures the level of SARS-COV-2 IgG antibodies in your blood from 0 AU/mL to 40,000 AU/mL. Antibodies decline over time at rates varied from person to person.

What do your results mean?

A positive result (≥50.0AU/mL) means your immune system may have sufficient antibodies to protect against and prevent severe symptoms, hospitalisation, and death caused by COVID-19.

A negative result (<50.0AU/mL) means your immune system may not have developed sufficient antibodies to protect yourself against COVID-19.

Feel comfortable going to public places
four star review
Understanding my protection against COVID-19 empowers me to make better decisions in my daily life and feel comfortable going to public places.
Alex
Confident to make travel plans
five star review
I’m more confident to make travel plans for myself and my family having knowledge that I can fight the virus if I do come in contact with it.
Christie
Great tool for monitoring my levels
five star review
It was interesting to find out if my antibody levels are still high enough to protect me from severe COVID-19 symptoms a few months after the vaccine. It’s a great tool for monitoring my levels easily.
Kevin
Glad to see I’m well protected
five star review
I did my COVID-19 antibody test 3 weeks after I received my booster shot. I'm glad to see I've got 14000+ Au/ml antibodies as I know I'm well-protected against COVID-19. Even if I got infected, I believe I will not experience severe symptoms and will get well very quickly.
Chris
Makes me feel secure
five star review
Knowing that I have 28 times more antibodies than the minimal threshold makes me feel secure. It's valuable to learn that I have adequate protection against COVID-19.

I figured out the cause of my rash!

My rash issue has been bothering me for quite a while, but I never had time to try find a real solution until I saw SnapShot! After getting my results I tried an elimination diet and it ACTUALLY fixed my rash. Overall worth it!

Nicole - Food Sensitivity Test

Convenient and totally worth it!

I was mainly attracted by the price, as it isn’t cheap doing this type of test outside. Secondly, it was very convenient as I could draw my blood anywhere and anytime, and avoid dealing with having to go to 
the clinic

Sam - Food Sensitivity Test

Finally understand why my face gets red easily…

I’ve always suspected I am sensitive to cakes. 
Every time I eat cakes, my face gets really red! 
After I did the test, I found out I was sensitive to egg white. I could do it at home and review my results on the App!

@jadelamm - Food Sensitivity Test

FOOD SENSITIVITY
I finally uncovered the mystery

I’d been experiencing mysterious stomach aches and bloating for months. After taking the Food Sensitivity test, I finally uncovered the mystery. The culprit? a sensitivity to eggs.

@xoy - Food Sensitivity Test

Total game changer

I never understood why blood tests always took so long and were so expensive. Testing at home, at a fraction of the time and cost is a total game changer.

Hannah - Food Sensitivity Test

100% HIGHLY recommended

If you’re scared of blood, this is something I would 100% HIGHLY RECOMMEND!!! The test doesn’t require you to prick your finger and it didn’t hurt at all for me.

Nathan - Heart Health Test

WOW. So easy

Doing your own blood test sounds scary but it honestly isn’t! The kit was VERY user friendly and collecting my sample was MUCH easier than I expected.

Ciara - Food Sensitivity Test

Literally saved me 
so much hassle

No fuss, no stress — the whole process took just under five minutes AND was done entirely at home!! It totally lived up to my expectations, 10/10 did not disappoint.

What does the test measure?
COVID-19 antibodies are proteins that your immune system makes to fight the COVID-19 virus and protect you from getting severly ill. They play a key role in building immunity against the virus. Antibody levels generally decline over time, after vaccination or prior infection. The antibodies amount, duration and declination rate vary from person-to-person.

This test kit measures your COVID-19 IgG antibody levels developed from a vaccination or past infection. You will find out your antibody level and whether it is a positive (≥50.0AU/mL) or negative (<50.0AU/mL) test result.

Our lab test for COVID-19 IgG antibody has an analytical sensitivity of 99.4%.
What can the test result tell me?
A positive antibody test result indicates your immune system may have sufficient antibodies to prevent severe symptoms, hospitalisation, and death caused by COVID-19.

A negative result means your immune system may not have sufficient antibodies to protect yourself against COVID-19.
What factors could affect my test result?
Immunocompromised individuals may have reduced antibody levels from vaccination and past infections.

Immunocompromised patients who have COVID-19 infection may have a delayed antibody response and produce levels of antibody which may not be detected as positive by the assay.

The persistence of a SARS-CoV-2 immune response has not been fully established. Negative results may be observed due to a decline in antibody titer over time.
Who is this test suitable for?
This test may be of particular interest to:

Individuals who want to monitor their antibody levels over time and who have been partially or fully vaccinated for at least 2 weeks

Individuals who have recovered from COVID-19, more than 2 weeks after symptom onset, to understand the status of their COVID-19 antibody levels

Individuals who want to understand their COVID-19 antibody levels from previous vaccines and before receiving a booster shot

Individuals who have not been previously diagnosed with COVID-19 or received COVID-19 vaccine and want to know if they have been previously exposed to the SARS-CoV2 virus

The test is intended for adults above age 18 only.

Note:
An antibody test is not recommended:

Until at least 14 days after the onset of symptoms for those who have been recently infected.

For those who have recently been vaccinated, it typically takes 2 to 3 weeks for your body to make antibodies after the first dose of vaccination.
