To perform a Down Syndrome test, the doctor will draw blood from the mother to check for DNA fragments. These pieces of DNA are between 25 and 30 base pairs long, and match a specific DNA chromosome. The researchers counted the number and types of gene fragments on each chromosome. Women with Down syndrome had higher numbers of DNA fragments from Chromosome 21 than those who didn't have it.
Screening tests estimate the risk of a baby having Down syndrome
Screening tests are used to estimate the likelihood that a developing baby will have Down syndrome. A one-in-1,000 chance that a baby will have Down syndrome means that one thousand babies will be born with the condition. The normal number is 999. This is the National Screening Committee's cutoff point for identifying a woman at risk of having a Down syndrome baby.
Screening tests can include a blood test to determine the fluid levels of a baby, as well as age, gender, race, smoking status and gestational date. The results of these screening tests will be used to calculate the likelihood that a baby may have Down syndrome. Although screening tests are very accurate, there may be abnormal results. It is crucial to be fully informed about the risks of these screening tests before undergoing any medical procedures.
Down syndrome is diagnosed by diagnostic tests.
There are many diagnostic tests that can be used to diagnose Down syndrome. These include ultrasound and blood testing. These tests have higher false-positive rates than other tests that are performed later in the pregnancy. In case of abnormal ultrasound results, your doctor may recommend an amniocentesis, or sample of the amniotic fluid, to determine if a baby is affected by Down syndrome. A quadruple screen can be used to detect neural tube defects or brain and spine cord defects. These tests are usually done at approximately fifteen to twenty-four weeks of pregnancy. If you're at high risk for any birth defects, your doctor may order a sample of your amniotic fluid to count chromosomes.
Ultrasound screening is another method of detecting Down syndrome in a woman's womb. This requires the woman to place a special gel onto her abdomen. Also, a small blood sample is taken. The ultrasound transducer will then send sound waves through the fluid. They deflect off the structures in the uterus. These structures are dense and determine the speed at which sound waves bounce back. The computer will then analyze this information and convert it into an image for the fetus.
Screening tests are invasive
Screening for Down syndrome is invasive. This is true regardless if they are associated with the possibility of miscarriage. Recent research shows that current invasive tests are no better than theoretical NIPD testing. Interestingly, nearly half of all women surveyed declined to undergo these tests, and one-third of those women indicated they would not have such a test. Still, some women may opt to go through these tests if they believe they are at no risk for miscarriage.
Although the screening test for DS has made enormous progress since the early 1980s, further improvements are needed. Today, the screening test for DS can be performed on between 5% and 10% of women. False negative results are reported in approximately 60% to 80%. Unfortunately, these tests are associated with significant risks and a high rate of false-positives. In 2008, screening for DS had resulted in the miscarriage of 400 babies without the disorder.
FAQ

What does "health promotion" mean?
Health promotion means helping people to stay well and live longer. This promotes health rather than treating existing diseases.
It covers activities such:
-
Eating right
-
Sleeping enough
-
exercising regularly
-
Staying active is key to staying fit
-
Do not smoke
-
managing stress
-
Keep up with vaccinations

learning how to cope with chronic illnesses.
What will happen to the health care industry if Medicare is eliminated?
Medicare is an entitlement program which provides financial assistance for low-income people and families who are unable to afford their premiums. This program covers more than 40 million Americans.
Millions of Americans would be without coverage if this program was not in place. Private insurers will stop offering policies for people with pre-existing conditions.
What is the distinction between the health service and the health system?
Health systems can be more than just providing healthcare services. They encompass all aspects of the life context, including education, employment and social security.
Healthcare services focus on specific conditions like cancer, diabetes and mental illness.
They can also refer to the provision generalist primary healthcare services by community-based doctors working under the direction and supervision of an NHS hospital trust.
What should I know about vaccines?
Vaccines offer a way to keep your body healthy and are extremely safe. They work by giving you immunity against certain diseases. Vaccinations are given during the adolescence and childhood. Your doctor will recommend when you should get vaccinated.
What information should I have about immunizations
Immunization is the process that stimulates the immune response to a vaccination. Immunization is the process by which the body makes antibodies (immunoglobulins), that protect against infection.
What are medical systems and what do they mean?
Medical systems are designed so that people can live longer, more fulfilling lives. They ensure patients receive the best medical care, when and where they need it.
They make sure that the right treatment is provided at the right time. They also give information that allows doctors to provide the best possible advice to each patient.

What are the key segments in the Healthcare Industry?
The healthcare industry is made up of key segments such as medical devices, pharmaceuticals and diagnostics, biotechnology, therapy, health information technology, medical equipment, and other medical devices.
Defibrillators, blood pressure monitors (defibrillators), stethoscopes, and ultrasound machines are some examples of medical devices. These products are used to diagnose and prevent or treat disease.
Pharmaceuticals are medicines prescribed to relieve symptoms or treat disease. Some examples include antihistamines and antibiotics.
Diagnostics are tests that are performed by labs to diagnose illness or injury. Examples include blood tests, urine samples, CT scans, MRI scans, X-rays, etc.
Biotechnology is the use of living organisms, such as bacteria, to create useful substances that can then be applied to humans. There are many examples, including vaccines, insulin, or enzymes.
Therapeutics are the treatment of diseases and symptoms that is administered to people to relieve them. These therapies can include drugs or radiation therapy.
The computer software programs called health information technology help doctors and their teams to manage patient records. It helps them keep track of which medications they're taking, when they should take them, and whether or not they are working properly.
Equipment used in the diagnosis, treatment, and monitoring of medical conditions or illnesses is called medical equipment. Examples include dialysis machines, pacemakers, ventilators, operating tables, etc.
