Read more about the Abbott diagnostic test here (opens external link).

Tests are not suitable for children as the blood collection can be difficult.

How do I get my results and how long will they take?

When you register for a test on our website you will have access to your own dashboard. We will upload your laboratory results to the pdf section, these cannot be sent over email as this may be insecure. You will also need to read and accept the terms and conditions of the test accuracy.

If you have bought a test for somebody else they will need to subscribe for a free account.

Due to a high demand some tests are taking over a week for results to return.


Important symptom checker questionnaire

We will also send you a questionnaire to complete via email or if you follow this link to the life1000 covid symptom questionnaire. To help us detect the true number of people who have been exposed to coronavirus it is essential that you fill this out as it will help us to correlate symptoms or lack of symptoms with results.

If you have a positive test we are legally obliged to notify Public Health England (PHE) of this. Coronavirus is a notifiable disease and it is important to keep track of the number of confirmed cases in the UK.

Instructions on how to take blood- IMPORTANT

We know that taking blood at home can be tricky however during shut-down we do not have the option of doing this in our clinics. It can be tricky at first, reading through the tips should make it easier. 


Make sure you are well hydrated.

Make sure to stand at a low table, gravity helps the blood flow.

Have your hands below your elbow.

Soak your hand in warm water this is essential to help collection.

Exercise by swinging your arms around in 15 large circles.

Remove the tip of the lancet gently twisting it as you remove, if you force it, this may affect the spring mechanism inside.

Pressing firmly with hand on a hard surface at the corner of the finger helps the lancet work better and makes it less painful.

  • Get everything you need laid out on the table in front of you.Try to use a low table so that you are standing above the table.
  • If your hand is below your elbow this helps blood flow more easily when you prick your finger with the lancet gravity helps your blood flow
  • The plastic holder has a small slot that can hold the blood bottle, take the lid off so it is ready when you prick your finger.Soak your non-dominant hand in warm water and do a little exercise to get your blood flowing, swing your arms around in large circles 15 times.
  • Placing your hand on a hard surface with your palm facing up and pressing firmly helps the lancet work properly.
  • The lancet has a protective cover that can be difficult to remove. Remove the tip of the lancet gently by twisting the tip several times whilst holding the side of the lancet, this should then allow you to gently remove the protecting nib if you force it this may affect the spring mechanism inside. This is where the needle emerges from. If you have used your lancets it is possible to open the case and use the needle directly.
  • Wipe your finger with the alcohol wipe.
  • Prick the corner of your fingertip- try your ring finger or your little finger whilst pressing firmly against it.
  • Massage.

Massage your finger from your knuckle to the first finger joint.

Don’t squeeze too hard or too close to where you have pricked your finger.

  • As each drop collects gently touch against the edge of the bottle.
  • If it takes more than 2 minutes to fill a tube and the blood has stopped flowing:
    • Rewarm your hand in warm water
    • Do some more exercises
    • Reprick the same finger with a fresh lancet
  • Once filled, push the cap on until you hear a click then invert the tube 10 times to mix the blood with the regent in the bottle.
  • Make sure to fill out the label and stick it on the bottle.
  • Make sure to fill out the form on the other side of the instructions form.
  • Place the tubes in the plastic holder along with the form and place these inside the plastic bag.
  • POSTAGE: As first class post is taking over 1 week to arrive we strongly suggest that you send this guaranteed first class before 1pm.

Will I be immune from coronavirus forever?

Immunologists are still studying how long immunity will last for if you have had coronavirus infection. We think it will behave like other Coronaviruses SARS and MERS in which case immunity will be at least for 3-4 months after your test. Whether you will still be immune next year is hard to say at the moment.

How do I get a test?

When we have availability you will be able purchase a test on our website and we will send a kit to you. The instructions on how to take your blood and how to send the test back will be in the test kit. We hope the tests will be available soon.

Home test kit verus ELISA laboratory testing

Home testing kits use a process called lateral flow. In these blood is dropped in to a plastic cassette and it then soaks a medium that has a marker for covid-19 antibodies this is a similar technique as that used in pregnancy tests.

ELISA does this process in a laboratory and so allows a higher detection rate with a greater accuracy and it measures the amount of antibody present.

What do I do if I have had a positive test but had no symptoms?

Current advice is that if you have a positive test you should isolate for 7 days.

If you have had a positive test but no symptoms it can mean two things:

  1. That you have been exposed to corona virus but your body was able to deal with the virus and build an immune response. Although we cannot say for sure it seems like a positive IgG result means that you will be immune to catching it again, certainly for a few months. Why can we not say 100%? There have been reports of individuals being re-infected but many of these cases have been disputed.
  2. That at the time of testing you had been infected but it was too early to show symptoms and you may go on to show symptoms.
