The Rh Factor
Malangnya, RhIg tidak akan berfungsi untuk wanita Rh-negatif yang telah sensitif (tubuhnya telah menghasilkan antibodi ke sel-sel Rh-positif) oleh kehamilan, keguguran, pengguguran, atau transfusi sebelum ini.
Apakah rawatan untuk penyakit Rh?
Jika bayi anda yang belum lahir adalah Rh-positif, doktor anda perlu mengukur tahap antibodi dalam darah anda semasa kehamilan berlangsung. Jika tahap antibodi yang tinggi dijumpai, ujian akan diberikan untuk membantu menentukan sama ada bayi sedang mengalami anemia (tanda penyakit Rh) dan jika demikian, betapa teruknya itu. Ujian ini mungkin termasuk amniosentesis dan prosedur lain yang disebut cordocentesis, di mana doktor, dipandu oleh ultrabunyi, memasukkan jarum nipis melalui perut ibu ke korda untuk mengambil sampel darah.
Berdasarkan keputusan ujian, seorang doktor boleh menasihati mendorong buruh lebih awal, sebelum antibodi ibu memusnahkan terlalu banyak sel darah janin. Atau dia mungkin merawat janin dengan pemindahan darah, biasanya menggunakan cordocentesis, seawal minggu kehamilan ke-18.
Selepas penyerahan, jika bayi mempunyai penyakit kuning, dia boleh diberikan fototerapi - diletakkan di bawah lampu biru khas. Jika jaundis tidak bertindak balas terhadap fototerapi, atau jika bayi itu anemia, pemindahan darah mungkin diperlukan. Tetapi beberapa kes penyakit Rh sangat ringan sehingga mereka tidak memerlukan rawatan.
Dengan penggunaan Rhyg yang meluas, beberapa wanita hari ini perlu bimbang tentang penyakit Rh. Anda boleh melindungi bayi anda dengan mempelajari status Rh anda dan, jika anda adalah Rh-negatif, mengikuti nasihat doktor anda.

FAQ - 💬
❓ What is Rh factor?
👉 Rh factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you're Rh positive. If your blood doesn't have the protein, you're Rh negative. The "+" or "–" you might see after your blood type refers to Rh positive or Rh negative.
❓ What is Rh factor and why is it important?
👉 The Rh factor is one of the proteins on RBCs used to indicate whether the blood of two different people is compatible when mixed – such as blood of a mother and her baby at birth. It is routine and important that the Rh factor for a mother and unborn child be determined during pregnancy.
❓ What happens if you have the Rh factor?
👉 During a pregnancy, Rh antibodies made in a woman's body can cross the placenta and attack fetal blood cells. This can cause a serious type of anemia in the fetus in which red blood cells are destroyed faster than the body can replace them.
❓ What does it mean if Rh factor is positive?
👉 Rh factor is a protein that's found on some people's red blood cells. If your red blood cells have the protein, you're Rh-positive. If your red blood cells don't have the protein, you're Rh-negative. Being Rh-positive or Rh-negative doesn't affect your health.
❓ What kind of blood is Rh negative?
👉 The red cells in your blood can be A, B, AB, or O. The red blood cells also have a protein that is called Rh on the surface of the cell. Your blood can be Rh positive, which means that you have the Rh protein, or Rh negative, which means that you do not have the Rh protein.
❓ Who has Rh negative?
👉 Only about 15% of the United States population has Rh-negative blood. There are specific pros and cons of having this blood type. For example, people who are Rh-negative may be immune to some of the effects of the parasite called Toxoplasma.
❓ What happens if the mother is Rh negative?
👉 If the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. The mother's body makes antibodies against the fetal blood cells. These antibodies may cross back through the placenta into the developing baby. They destroy the baby's circulating red blood cells.
❓ What happens when mother is Rh positive?
👉 Rh antibodies are harmless until the mother's second or later pregnancies. If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign. Her antibodies will pass into the baby's bloodstream and attack those cells.
❓ What is the healthiest blood type?
👉 Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
❓ What are the 3 rarest blood types?
👉 The rarest blood types are: B negative(B -ve), which is found in 1.5 percent of the total population. AB negative(AB -ve), which is found in 0.6 percent of the total population. AB positive(AB +ve), which is found in 3.4 percent of the total population.
❓ What blood type is the healthiest?
👉 Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
❓ What is the meaning of Rh factor?
👉 Rhesus (Rh) factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you're Rh positive. If your blood lacks the protein, you're Rh negative.
❓ What is the importance of Rh factor and blood typing?
👉 Blood typing is a system of classifying blood based on the antigens present on or missing from the surface of RBCs. This approach to grouping bloods can prevent the severe complications that can occur from interactions between incompatible blood types. In this article, we discuss the importance of the Rh factor and blood typing.
❓ What is Rh positive blood?
👉 Rhesus (Rh) factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you're Rh positive.
❓ What is the Rhesus factor?
👉 The Rhesus factor, or Rh factor, is a certain type of protein found on the outside of blood cells. People are either Rh-positive (they have the protein) or Rh-negative (they do not have the protein). This distinction mostly matters when you are Rh-negative and your child is Rh-positive.
