Antenatal screening is the process of identifying those at high risk of a disorder. Prenatal diagnosis establishes whether or not the disorder is definitely present. Screening is used to select a high risk group so that they can be offered prenatal diagnosis.

First trimester screening is a combination of fetal ultrasound and maternal blood testing. This screening process can help determine the risk of the fetus having certain birth defects. Second trimester prenatal screening may include several blood tests called multiple markers.

“It’s optional, but not required.” Most women get prenatal genetic testing to know what the risk is before the baby is born, Greiner said. They would rather know the information during pregnancy than at birth so they can make plans and decisions ahead of time or gain further knowledge, she explained.

Your blood will be tested for: blood count, blood group and Rhesus status (positive or negative) sickle cell and thalassaemia. infectious diseases (hepatitis B, syphilis and HIV)

A human chorionic gonadotropin (hCG) urine test is a pregnancy test. A pregnant woman’s placenta produces hCG, also called the pregnancy hormone. If you’re pregnant, the test can usually detect this hormone in your urine about a day after your first missed period.

A urine pregnancy test can find the HCG hormone about a week after you’ve missed a period. The test can be done in a health care provider’s office or with a home test kit. These tests are basically the same, so many women choose to use a home pregnancy test before calling a provider.

Pregnancy. Anecdotal evidence suggests that bright-yellow urine may be an early symptom of pregnancy.

Darker yellow urine is common when you’re dehydrated because the urine is more concentrated.” For example, your first pee of the morning tends to be more concentrated and therefore looks darker than it would later on in the day.

Why does urine smell like ammonia while pregnant? In most cases, an unusual ammonia-like vaginal smell during pregnancy is caused by changes in urine. This can be due to lifestyle factors, such as dietary preferences, dehydration, and supplement use.

If you’re dehydrated, you may notice that your urine is a dark yellow or orange color and smells like ammonia. Most people only experience minor dehydration and don’t require medical treatment. Drinking more fluids, especially water, will generally cause urine odor to return to normal.

Some foods and medications, such as asparagus or certain vitamins, can cause a noticeable urine odor, even in low concentrations. Sometimes, unusual urine odor indicates a medical condition or disease, such as: Cystitis (bladder inflammation) Dehydration.

Semen is alkaline and often women find they notice a fishy smell after having sex. This is because the vagina wants to be slightly acidic, but if it’s knocked out of balance by the alkaline semen, and it can trigger BV.

Dark urine is most commonly due to dehydration. However, it may be an indicator that excess, unusual, or potentially dangerous waste products are circulating in the body. For example, dark brown urine may indicate liver disease due to the presence of bile in the urine.

Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is. Pigments and other compounds in certain foods and medications can change your urine color.

A fishy smell in urine may be caused by the presence of bacteria, TMA, or an interaction between them. According to a study from 2013 , most healthy people produce chemicals that break down TMA, which stops them from smelling like fish, even when they have eaten fish recently or have a lot of bacteria in their systems.

Because people tend to sleep for several hours without having a drink, their urine is normally darker when urinating first thing in the morning. Darker urine during the day or evening may be one of the signs that someone is dehydrated meaning they are not drinking enough fluids.

Normal urine should be pale yellow. It should be clear and free of clouds or particles. Urine can occasionally turn a bright yellow color.

For the average adult, taking 4 to 10 pee trips in a 24-hour period is considered normal. The reason you want to avoid overhydrating is because an excess of water dilutes your body’s electrolyte content. While rare, this can lead to water intoxication.
