Understanding your antibody test results
Taking an antibody test will let you know if it’s likely you’ve had COVID-19 in the past.
What does a positive result mean?
If you test positive for antibodies it means that there were COVID-19 antibodies in your blood sample. This means your body has produced a response to COVID-19, either from having the virus or the COVID-19 vaccine.
The level of antibodies can suggest your body’s response to either the virus or vaccine. As COVID-19 is still a fairly new virus, we don’t know yet what the significance of the level’s value or whether this might change with time and how long you might have this immune response.
What does a negative result mean?
Testing negative for COVID-19 antibodies means that there were either no antibodies or the levels were too low to be of any significance.
You’ll be told your antibody levels are less than 0.4U/mL. This means you most likely haven’t had COVID-19 or had the vaccine.
Antibody testing after the COVID-19 vaccine
If you’d like to test your immune response after the COVID-19 vaccine, you can do this 14 days after your first dose.
You can get tested again from 14 days after you second vaccine, to see if your antibody level has changed.
No vaccine or antibody test is 100% effective. There is a small chance you’ll test negative even though you’ve had the vaccine.
Antibody testing after having COVID-19
Not everyone who’s had COVID-19 will test positive for antibodies. This can be due to low levels of antibodies in your system or the time that’s passed since having the virus.
The test has specificity of 98.8% and a sensitivity of 99.8%.
This means that:
- Out of 1000 people tested, 12 will get a positive result when they’re actually negative. This is called a false positive.
- Out of 1000 people with antibodies, 2 will test negative even though they’re positive. This is called a false negative.
- 1 antibody test kit
- Adults aged 18 and over
Warnings and cautions

How to use
- The side of your little finger is the best location for collecting your sample.
- Wash your hands in warm soapy water. It’s much easier to collect your sample if your hands are warm. Dry them thoroughly with a clean, dry towel.
- Using the Acotip Swab clean the selected little finger. Wipe dry with a clean tissue.
- Remove one lancet from the bag. Twist and remove the blue stick. The lancet is ready to use.
- Position the lancet against the side of your little finger. The lancet will activate when pressed firmly against your skin. Stand up rather that sit down when collecting your blood drops.
- This will puncture the skin and a small drop of blood will form. Wipe away the first drop of blood with a clean tissue.
- Holding your arm and hand downwards, milk your hand and little finger to help the blood drop into the collection tube.
- Fill the blood collection tube to the TOP LINE FILL. If you’re unable to collect enough blood, try rubbing the puncture with a dry tissue to help form new blood drops or use the second lancet on your other little finger.
- Once filled, stop collecting and apply the plaster to your finger. Push on the cap of the collection tube until you hear a click.
- Fill in the label in your pack with your details. The affix by wrapping the label around the tube. Unlabelled samples cannot be accepted.
- Place the collection tube in the wallet provided, and the wallet in the test box along with any used lancets. Seal the box, place it in the self-addressed packaging and post as soon as possible from any UK Royal Mail post box.
