The EldonCard blood type test kit uses the basic forward antibody technique of blood hematology for quick and simple determination of your blood type.

EldonCard is a newly developed patented test that determines your blood group, which can be used anywhere. It is the cheapest approach to get the most accurate results rapidly within a few minutes without the need for conventional laboratory testing and skilled technicians.

• The EldonCard blood type test kit uses the basic forward antibody technique of blood hematology for quick and simple determination of your blood type.
• The most common blood types are A, AB, B, or O, which are determined by the presence of respective antigens (specific proteins present over the red blood cells).

The presence of either of the antigens and special factors on the red blood cells known as the rhesus (Rh) factor determine the blood type. If the Rh factor is absent, then your blood type is Rh-negative, and if it is present, your blood type is Rh-positive.

EldonCard has four small circles, each incorporated with different antibodies.

• First circle: Named Anti-A and contains antibodies A
• Second circle: Named Anti-B and contains antibodies B
• Third circle: Named Anti-D and contains Rh antibodies
• Fourth circle: Control

When your blood is added to each of these sections, the antigens in your body react with antibodies on the EldonCard to form blood clots. Just by looking at the sections where the blood clots, you can easily determine your blood type.

If clots are seen in the fourth circle (control), it determines that the test is faulty, and you have to get blood grouping done by professionals in a laboratory.

How to read the EldonCard

EldonCard is a small card that contains antibodies incorporated in the circles.

Reading blood clots in the circles will determine your blood group as follows:

• A positive:
  • A positive means you have antigens A and rhesus (Rh) factor in your blood.
  • Blood clots are seen in the first and third circles in the EldonCard.
• A negative:
  • A person with A negative blood has antigen A but no Rh factor in the blood.
  • Blood clots are seen only in the first circle on the EldonCard.
• B positive:
  • The blood contains both antigen B and Rh factors.
  • Blood clots are seen in second and third circles on the EldonCard.
• B negative:
  • The blood contains antigen B but no Rh factor.
  • The EldonCard shows blood clots only in the second circle.
• AB positive:
  • AB-positive blood contains both types of antigens A and B, as well as the Rh factor.
  • Blood clots are seen in the first, second, and third circles on the EldonCard.
• AB negative:
  • This blood type contains both A and B antigens, but the Rh factor is absent.
  • Blood clots are seen in the first and second circles on the EldonCard.
• O positive:
  • A person with O-positive blood does not have the antigen A or B in the body, but the Rh factor is present.
  • The EldonCard shows blood clots only in the third circle.
• O negative:
  • An O-negative type of blood does not contain any antigens in the blood.
  • Antigens A and B and Rh factor are absent.
  • The EldonCard will not trigger any blood clots to develop.

What are the advantages and disadvantages of EldonCard?

Here are the advantages and disadvantages of EldonCard blood tests:

Advantages

• EldonCard is easily accessible and can be used anywhere; it is user-friendly and can be used by anyone but requires some caution.
• It is a secure test in most cases.
• It can be used to determine the blood group instantly in emergencies such as:
  • Traumatic situations where the person needs an immediate blood transfusion
  • Bedside blood grouping of a person without the hassle of waiting for a lab report
  • Determination of the presence of rhesus factor in a pregnant woman
  • Testing for blood groups in schools and organizations

Disadvantages

• EldonCard does not have any serious disadvantages, and it is almost 99 percent accurate.
• Only very rare blood group types cannot be determined by the EldonCard.
• The blood grouping test needs a conventional type of testing by professions only if blood clots are seen in the fourth circle (control).
• Test kits should be used within 24 hours once exposed to the air.
• These kits do come with an expiration date from the date of manufacture and should be kept at 98.6°F (37°C) for accurate results.
• This testing requires pricking the finger for the collection of blood, so it should be done by adults to prevent any unwanted accidents.

EldonCard summary

• Correct blood grouping is obtained by comparing blood sample coagulation findings on pretreatment areas of the blood typing test card to a graphic picture chart.
• The picture chart contains images that show how and where blood clots form for a particular blood type.
• To create a permanent record, the test card should be filled out with personal identity information and laminated with the accompanying plastic sheet.
