You may need to know blood type information for medical reasons, to get an international visa, or to simply get to know your body better. You can estimate your blood type based on your parents' blood type, but to be more accurate, you'll need to do a blood type test. If you don't want to see a doctor, you can do it yourself at home using a simple blood test kit.
Step
Method 1 of 2: Self Determining Blood Type
Step 1. Ask your parents blood type
If the blood types of both your biological parents are known, the chances of your blood type can be narrowed down. In most cases the blood type only needs to be estimated, using an online blood group calculator or viewing the following list:
- parent O x parent O = child O
- parent O x parent A = child A or O
- parent O x parent B = child B or O
- parent O x parent AB = child A or B
- parent A x parent A = child A or O
- parent A x parent B = child A, B, AB or O
- parent A x parent AB = child A, B or AB
- parent B x parent B = child B or O
- parent B x parent AB = child A, B or AB
- AB's parents x AB's parents = children A, B or AB
- Blood type also includes the "Rh factor" (+ or -). If both of your parents have Rh- blood types (such as O- or AB-), you will also have Rh-. If one or both of your parents have Rh+ blood type, you can't tell if your blood type is + or – without going through a blood test.
Step 2. Call a doctor who has tested your blood
If your doctor has saved your blood type, you only need to contact him or her to ask questions. However, the doctor will only have this information in his file if your blood has been drawn and/or tested before. You may have had your blood type tested for the following reasons:
- Pregnancy
- Operation
- Organ donor
- Blood transfusion
Step 3. Purchase a blood type test kit
If you don't want to visit a doctor or donate blood, you can buy a blood type test kit at a pharmacy or online. The price of these tools ranges from Rp. 190,000 to Rp. 350,000, 00. In the instructions for use, you are usually asked to wet some labeled paper on a special card, then you are asked to prick your finger and drip a little blood on the surface of each labeled paper. the. When dripping blood onto paper, make sure you follow the instructions given. Pay attention to which paper (or vial containing a chemical, in other test kits) causes the blood to clot (agglutinate) instead of scattering. Clotting is the reaction of a chemical-a reagent or chemical reagent contained in a paper or bottle-against your blood. After you have completed the test with all cards or liquids/chemicals, check your blood type using the instructions provided on the kit or following the list below:
-
First, check the paper labeled "Anti-A" and "Anti-B" for clumping:
- Clumping occurs (only) in Anti-A, meaning you have blood type A.
- Clumping occurs (only) in Anti-B, meaning you have blood type B.
- Clumping occurs in Anti-A and Anti-B: your blood type is AB.
-
Next, check the paper labeled "Anti-D":
- Clumping: Your blood type is Rh positive. Add sign + on your blood type.
- No clots: your blood type is Rh negative. Add sign - on your blood type.
- If the control paper (plain paper) is causing the clot, or if you're not sure on which paper the blood is clotting, try another card. Any blood tests performed by ordinary people tend to be less convincing than tests carried out by skilled medical personnel.
Method 2 of 2: Visiting a Health Care Center
Step 1. Ask your doctor for a referral for blood tests
If your doctor doesn't have your blood type on file, you can also ask for a blood test. Call your doctor or visit his or her practice and ask for a referral for a blood test.
Try saying something, like, "I want to know my blood type. Can a doctor give me a referral for a blood test?"
Step 2. Visit a health clinic or puskesmas
If you don't have a primary doctor, you can do a blood test at a health clinic or health center. You just need to come there and ask the officer to check your blood type.
You may need to call ahead to find out if a blood test is a service offered by the health clinic or health center
Step 3. Donate blood
Donating blood is an easy way to determine your blood type while helping others. Look for a blood donor service center, such as the local Indonesian Red Cross, or wait until a school, church or public service center announces a blood donation movement. If you participate in donating blood, ask the staff to tell you your blood type. Your blood is usually not tested right away, so it may take the staff several weeks to deliver the results by phone or letter/e-mail.
- Before choosing an agency to donate your blood to, you may need to call ahead to make sure that the agency is willing to tell you your blood type. You know, the Indonesian Red Cross (PMI) provides a free blood type examination service for donors.
- Keep in mind that there are some special requirements that must be met before you can donate blood. Some conditions may also prevent you from donating blood, such as high-risk habits, travel abroad, being sick, or previously undergoing treatment for a chronic illness.
Step 4. Visit a blood service center, if this agency is in your area of residence
The blood service center always provides free service for anyone to undergo a blood test and find out their blood type.
If you live in Canada, visit the official blood Canada website and look for information on the location of the "What's Your Type? This activity is a promotion that is routinely organized by Canadian Blood Services. Blood test results are instant, and participants can find out whether their blood type is common or rare, from whom they can receive blood, and to whom they can donate blood. Here, participants will also know the ABO blood type and the positive and negative Rhesus (Rh) factor. In Indonesia, free blood type checks are sometimes organized by certain agencies, such as the Health Service, school agencies in collaboration with PMI, etc. In events related to the community, the importance of knowing blood type is also given
Tips
- In addition to blood type, a person should also have a Rhesus or Rh factor test. If you have your blood group tested with the Red Cross or any professional organization, they will tell you your Rhesus factor. Rhesus factor is also called D. Your Rhesus factor may be D+ or D-. For example, if clots are seen in the A (Anti-A) and D (Anti-D) planes, the person has blood type A+.
- If you only know the blood type of one of your parents, you can create a punnet diagram (a punnet square - tabulated to predict all the possibilities that could arise in a marriage/cross) to estimate your probability of inheriting one of them. There are three alleles (alleles - alternative forms of genes that show variation and inheritance of traits) that determine blood type are: dominant allele IA and IB, and the recessive allele i. If your blood type is O, you have genotype ii. If your blood type is A, your phenotype is IAIA or IAi. Note: genotype is the invisible and heritable genetic makeup of an organism; while the phenotype is the trait of an organism that is seen by the five senses, as a combination of genotype and environmental factors.
