Genetic Testing (Definition)

Prenatal testing for genetic problems may be done before or after conception. Testing for spina bifida or Down syndrome is done after a pregnancy is established. Besides the couples listed above, counseling and diagnosis are also recommended for mothers over the age of 35, and those who have received abnormal screening test results, such as alpha-fetoprotein (AFP). For more information about the alpha-fetoprotein test, and when and why you might have it, see alpha-fetoprotein. For those who may be at risk, genetic counseling and prenatal diagnosis are used to help ...Read more

On one side of my family runs multiple sclerosis and im sure whether or not i will end up having it is well. Is there any test for early detection?

On one side of my family runs multiple sclerosis and im sure whether or not i will end up having it is well. Is there any test for early detection?

Maybe: First, more than 80% of all ms cases are non-familial. Second, at most you might have a 5% risk. Third, even if your MRI showed lesions consistent with radiologically isolated syndrome, it would not be appropriate to treat until you demonstrate clinically definite ms, or your spinal fluid is showing active abnormalities. Your risk is low, but seek neurological consult if you are worried. ...Read more

How do I know if my baby has an allergy from a tcertain type of food? Is there a specific test that can be done once for all foods?

How do I know if my baby has an allergy from a tcertain type of food? Is there a specific test that can be done once for all foods?

No universal test: Testing is rarely 100% accurate & i know of no universal tests for food allergies.Some labs have a variety of blood studies that correlate with some food reactions, but allergists usually pair the blood study with pin prick tests. All of which can falsely suggest allergy. Sometimes just eliminating the material from the diet for 2 wks, seeing benefit, & seeing pbs if restarted tells u. ...Read more

If alzheimer's disease runs in my family, is there a test I can have done to see if I will develop it in the future?

If alzheimer's disease runs in my family, is there a test I can have done to see if I will develop it in the future?

Yes: If several have alzheimer, particularly at early ages, then you may want to consider gene (dna) testing. Enter omim in browswer, search on alzheimer, look at alz-1, 2, and 3 entries for genes involved. On right of entry hit link to genetests that shows labs doing testing. I strongly recommend seeing a clinical geneticist or neurologist to discuss the value and burden of testing. ...Read more

Is rds hereditary, is there a test I can have to make sure my next child doesn't have the same problem?

Can happen to all: Typical rds results when a baby is born before the lung has finished developing and can happen to any baby born prematurely. Like having a new house without painted walls, premi's have lung tissue without a chemical on the walls to help aerate the lungs. Some factors like stress increaselung maturity while diabetes in mom can slow it. Your best prevention is to keep healthy & deliver on time. ...Read more

Can you tell me what you suggest if my aunt has cancer, then is there a low/medium/high chance that my dad, and then i, may also have inherited the genes?

Can you tell me what you suggest if my aunt has cancer, then is there a low/medium/high chance that my dad, and then i, may also have inherited the genes?

Depends: ...On the kind of cancer, the age at which she got it, the number of people in the family, and lots of other factors. Most cancers are not caused by an inherited gene defect. If you are very concerned, talk to your doc and if he/she thinks is proper, you may need to see a genetics specialist. If your aunt is the only one with cancer and had it late in life, odds are that is not an inherited trait. ...Read more

How can I know if I have iron overload/hemochromatosis? What tests should be performed? I hear that there is a DNA genetic test kit for hemochromatosis, is that true?

How can I know if I have iron overload/hemochromatosis? What tests should be performed? I hear that there is a DNA genetic test kit for hemochromatosis, is that true?

Blood tests: Iron and TIBC (total iron binding capacity) can be used to detect iron overload (iron/tibc >45 increases suspicion). Hemochromatosis, one cause for iron overload, can be detected by a gene study. As a general rule, patients with hemochromatosis are referred to gastroenterologist for a liver biopsy, as iron overload can do significant damage to the liver. ...Read more

My mother died of stomach cancer at age 34. Is there a genetic test I can take to see if I will get it and likelihood of early death etc?

My mother died of stomach cancer at age 34. Is there a genetic test I can take to see if I will get it and likelihood of early death etc?

No routine test: It is possible but it is rare to have hereditary Stomach cancer. So it is unlikely that you have much risk for it. If you want to pursue it further, you should see a Gastroenterologist who can counsel you and may even find a genetic counselor to guide you further. An upper Endoscopy(EGD) can be done easily to look inside your stomach and also do a biopsy for H.Pylori infection which can cause Canc ...Read more

I : I am not an oncologist or a geneticist, so unfortunately I am not expert enough in these areas to answer your questions. You should speak with the doctor that ordered the testing for you and your child. They should either be able guide you in what you should do next or recommend someone who can. I have also linked to two websites below for the medical genetics and medical oncology departments at duke. You can try contacting them to discuss your concerns if your doctor is unable to help.

My husband and i are trying to conceive. What is the earliest to test for pregnancy? And what test is best to buy that will give early results?

My husband and i are trying to conceive. What is the earliest to test for pregnancy? And what test is best to buy that will give early results?

No preference: All of the home tests are comparable and potentially can turn positive even before you have missed a period. Hormone levels rise and become detectable about 8 days after conception, although only a blood test will detect them at the earliest stage. 10 to 12 days after conception is about the best you can do with home tests. ...Read more

While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
