With advances in technology, even if there was a problem with the prenatal development of your baby, doctors are able to respond sooner. This is all made possible due to technologies such as ultrasound. It is a common misconception that pregnancy testing takes place only once, at the beginning of your pregnancy. Nothing could be further from the truth - from ultrasounds to blood tests, you will be bombarded with test after test up until even the very morning of your delivery date.

1. Primary Testing

Quite a lot of blood work is performed initially for various reasons including whether you are Rh negative or positive, your immunity to viruses such as rubella, and whether you have a more serious condition such as hepatitis B, or HIV. At this initial visit you will also receive a physical and internal examination to check your capability for giving birth, and if necessary, a smear test.

2. High Risk Testing

Ultrasound, unfortunately, is not merely a tool that allows the mother to see her child before it is born, or to determine the sex of the child prior to childbirth. The real purpose of an ultrasound is very much the same reason that you might need to get an x- ray - there is something potentially quite wrong with you beneath your skin where a simple visual analysis is insufficient. Don't worry, however, this is actually a routine procedure carried out at 18 weeks for all pregnant women.

3. Ultrasounds Can -

- Determine early the gender of the baby
- Measure the placenta
- Check embryonic fluid composition
- Ensure the umbilical cord is not causing any complications
- Ensure there is no internal bleeding

4. Gestational Diabetes

Pregnancy testing against gestational diabetes is carried out on all pregnant women during their second trimester. This primarily involves fasting until the test, then drinking a special glucose drink, waiting a specified period of time and then checking the blood sugar level with a simple finger prick blood test. If the blood sugar levels are off the charts then you will have to go for additional blood testing at a later date.

5. Amniocentesis

You are only elidgeable for this level of testing if you are over 35 years of age or if you have a medical history in your family such as Down's syndrome. Usually carried out between 14 and 20 weeks of pregnancy, there is a slight risk of miscarriage as a result of this test so it is not compulsory.

6. Chorionic Villus Sampling

The most feared and invasive of all pregnancy tests, this is an exhausting test for a woman to endure. Carried out between weeks 10 and 13 of pregnancy. This test is only carried out when there is an absolutely urgent need to determine the health status of the baby.
