How to Find Out Your Blood Type at Home with Blood Type Kit
The home blood kit includes everything you need like slim sticks, straws, finger poker, and the most important thing Eldoncard. An Eldoncard is a piece of paper that has been made to react to your blood in some way. You just need to drop blood on it, spin it and finish!
Here is a more detailed tutorial on how to find out your blood type at home:
Step 1. Place all the components of the kit in front of you and then drop a drop of water on each circle of Eldoncard.
Step 2. Disinfect your fingers with an alcohol wipe first, and then puncture the fingers with a lancet.
Step 3. Squeeze your fingertips to get a big drop of blood. Use a plastic tool included in the kit to transfer a drop of blood to a card ring. Do this for each circle.
Step 4. Use the same plastic rod used for blood collection to spin the blood and water droplets together in each circle. Tilt the card in all directions for 10 seconds.
Step 5. Then, compare your circles of blood to find out your blood type.
Note: If you are afraid of using a lancet, there is actually no harm at all by using it. You just need to put it on your finger and take it away, then put it on your finger and take it off again. Then drink a glass of water. Then come back, put it on your finger, and take it away. Don’t worry about its little damage, you might even be unsure whether it’s working.
How to Find out Your Blood Type Without Drawing Blood
If you don’t want to draw blood, you can also use saliva. A person may be able to use a saliva sample to test their blood type because some people produce characteristic antigens in their saliva.
According to research sources in 2018, if a person does secrete these antigens in saliva, then a dry saliva sample can reliably indicate his blood type.
Note also that not everyone secretes these antigens, and this method does not necessarily indicate the presence or absence of the Rh factor.
