How long does it take for chorionic villus sampling results to come back?

The preliminary findings should be available within three working days. This will notify you whether a chromosomal disorder, such as Down syndrome, Edwards syndrome, or Patau's syndrome, has been discovered. If uncommon disorders are also tested for, it may take 2 to 3 weeks or longer for the findings to be returned.

This is a very important test because it allows doctors to find out early on if your baby has any birth defects. Also, with Down syndrome pre-natal diagnosis can help parents decide what future actions to take (such as having more children or undergoing amniocentesis/karyotyping).

Chorionic villus sampling is a procedure used to obtain samples of the developing fetus for examination. It is performed at about six weeks' gestation, just after the fetal blood vessels have developed enough to allow for easy access. The sample is taken from the chorion, the thin outer layer of the uterus that contains many blood vessels and connects the fetus to its mother.

This test is usually done on an outpatient basis. You may be asked to wait in a room until the procedure is over. Local anesthesia is given to the area where the needle will be inserted into the uterus. Then, a small piece of tissue containing several blood vessels and connected to the fetus is removed through a hollow needle.

There are no serious side effects associated with this procedure.

How long does a Western blot test take for Lyme?

Typically, test results are available in 1 to 2 weeks. Negative (normal): No band patterns appear at all on the membrane. Positive: At least one band appears on the membrane.

A negative result does not mean that you do not have Lyme disease. Many people with Lyme disease will not show any symptoms or only mild ones. Even if you don't feel sick, your body may still be fighting the infection. A negative result could also mean that you have been cured of Lyme disease.

A positive result should be followed up with testing of other family members who may not be aware they are infected, so they can be treated as well. The white blood cell test can help identify those who might not be symptomatic but could be spreading the bacteria around their body. This type of testing is called "serological testing."

Western blots are considered the "gold standard" for diagnosing Lyme disease because no other method is completely reliable. Other tests exist, but they may give false positives or negatives. For example, the enzyme-linked immunosorbent assay (ELISA) test can give false positives when used to diagnose early stage Lyme disease.

How long does it take to get lab results back for celiac disease?

You should receive the findings in roughly 1-2 weeks. The results will be discussed with you by your child's doctor. They may call you or come to see you in their office.

There are several different types of tests that may be done to diagnose celiac disease. Some of these tests can also help doctors find out if your child is at risk for other diseases or problems. Not all tests are used in every case, so not all children will have all of their symptoms checked through laboratory studies. Tests that can show damage to the intestinal wall from gluten include:

Biopsy - a small piece of tissue is taken from the intestine and examined under a microscope. This is the only way to know for sure if you or your child has celiac disease. A portion of a normal-looking piece of intestinal tissue shows signs of damage caused by gluten when stained with hematoxylin and eosin (H&E).

Gluten antibody tests - these check for antibodies against gluten in the blood. Antibodies are proteins produced by the body in response to foreign substances such as viruses and bacteria but also including gluten.
