Previously, there was a real lack of awareness that Anti-D was manufactured from human blood. This lack of awareness poses a real threat to women being able to make an informed choice.

While people often question the need for a blood transfusion, they rarely question the need for Anti-D. That begs the question of whether they really know what they are being offered. Most women want Anti-D anyway. But everyone has a right to know exactly what they are being offered. Sara explains the issues and evidence, answers key questions and shares information about what we do and do not know about Anti-D and related topics from research evidence and current thinking.

A vital resource for parents, professionals and birth workers. I think this is an important one to note near the top as well. Postnatal Anti-D is incredibly effective. Although the evidence on routine antenatal Anti-D is, according to the Cochrane review in this area, of low to very low quality. There are risks and downsides, paradoxes and wider issues. These are big decisions. They deserve our time and attention.

There is a theory that anything that could interfere with the integrity of the placental site — be it of pharmaceutical origin or related to manual interference such as fundal fiddling or early cord clamping or technological interventions like ultrasound — may increase the likelihood of fetal blood entering the maternal bloodstream. But there are no guarantees. Some women who have become isoimmunised after gentle, natural, unmedicated birth.

Instead, IgG appears to selectively disrupt B cell priming, although the exact mechanism remains obscure. While the applicability of animal models of AMIS to understanding the true mechanism of anti-D remains uncertain, the models have nevertheless provided us with insights into the possible IgG effects on the immune response.

This is perfectly normal and is usually not a problem. However, in about 1 in 10 pregnancies, these blood groups differ in one particularly important way: either the presence or absence of a protein on the surface of red blood cells.

It is now referred to as simply the RhD Factor. If you do not, you are known as RhD Negative. Sometimes, a small amount of blood can cross over from the baby's circulation in the placenta and enter the mother's blood stream.

This can happen at any time in pregnancy, but most importantly during the last 3 months of pregnancy if there is a trauma of some kind, and just before birth.
