Is there a genetic test for hemolytic disease of the newborn?

Is there a genetic test for hemolytic disease of the newborn?

Yes: Hemolytic disease of the newborn, causing yellow skin and eyes (jaundice) with anemia, is most commonly due to a "set-up"--a blood type difference between mother and child. Blood types are caused by genes at the ABO and other loci (rhesus being most damaging), with o type or rh negative moms making antibodies to red blood cells of a or b or rh+ fetuses (if mom is o and fetus ab, baby switched), . ...Read more

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

What is the treatment for hemolytic disease of newborn?

Various: Hemolytc disease can be mild and treated with bili lights. In extreme cases, it may be picked up early in pregnancy from an antibody screen. If positive, the antibody is identified. If a concerning antibodies present, the blood counts of the baby will be followed closely. Intrauterine transfusions may be required in these rare instances. ...Read more

What are the tests for hemolytic disease of newborn?

What are the tests for hemolytic disease of newborn?

Test for mom/baby: The baby will get test like coombs testing, hemoglobin or cbc, bilirubin tests and reticule yet counts. The coombs tests shows that an antibody is cause the hemolysis. The antibody specificity can be determined by additional tests. These antibody levels can be measured in mom and baby. Most of these antibodies will cause hemolysis. Some can cause decreased RBC production in the baby. ...Read more

What is the extent of drug testing for a newborn baby for example there is several kinds of opiates. Is there a test for each different one?

What is the extent of drug testing for a newborn baby for example there is several kinds of opiates. Is there a test for each different one?

Depends on situation: The routine newborn is not tested for drugs unless some suspicion is raised by the appearance or symptoms of the baby.If child protective services has a watch out for a given delivery, testing is routine & can be either a non specific screen or a more specific test.The more specific will differentiate opioids from the stimulants and cannabis. Once identified, no further id is needed for action. ...Read more

What is the extent of drug testing for a newborn baby for example there is several kinds of opiates is there a test for each different one or?

Varies: To begin with not all babies would be tested. In a few places the mom might have a urine screening, which is rather generic. However, if the mom is on a watch list & I need to check baby, the specimen is sent for rather specific chromatography which can define which if any specific drugs the kid was exposed to in the womb. ...Read more

Is there any risk of immuonmodulation treatment for Crohn's disease in a woman with the brca1 gene?

Is there any risk of immuonmodulation treatment for Crohn's disease in a woman with  the brca1 gene?

Jury is out.: There is no solid data on this to my knowledge. There are several potential immunomodulatory treatments ( which probably have their own independent risks ) and they are sometimes used in combination. Reports differ on risk but in general appears to be small and manageable. How this changes with brca1 ? ...Read more

For the pathologists, when testing for antibodies, if there is a perinuclear staining of some cells of a human pituitary, what could this indicate?

For the pathologists, when testing for antibodies, if there is a perinuclear staining of some cells of a human pituitary, what could this indicate?

Maybe adenoma: Perinuclear staining means that the cells stained around the nucleus, but it doesn't tell what exactly stained. Pituitary adenomas, which are benign tumors, can show perinuclear staining with an antibody to cytokeratin. Looking at staining patterns is one way to tell the difference between types of pituitary tumors. We need more information from your pathology report to answer this. ...Read more

Is there a genetic test in UK that can tell if a person is a poor metabolizer with Clopidogrel having two copies of each of the CYP2C19 gene.?

Is there a genetic test in UK that can tell if a person is a poor metabolizer with Clopidogrel having two copies of each of the CYP2C19 gene.?

Phenotype is the big: issue, not genotype, because we each live with the complex results of both genotype combined with all our complex internal controls, beyond the any gene or sets of genes alone. Since clopidgrel is a platelet suppressing, clot-slowing agent, best check clotting with & without whatever trial dosage. The best of the clotting tests is TEG, study: Thromboelastography, commonly used in hospitals. ...Read more

Is a woman with sc blood genotype a sickle cell carrier or patient. And what is the health implication of this especially during pregnancy?

Is a woman with sc blood genotype a sickle cell carrier or patient. And what is the health implication of this especially during pregnancy?

Hgb SC: Is a sickle cell syndrome but the genetics are different. A woman with HGB sc will pass either a HGB s gene, or a HGB c gene to her child. It is important to know what kind of HGB the father has-he should have a hemoglobin electrophoresis to find out how the child might be affected. Pregnancy complications are rare, but the baby can have a low weight, and rarely there are complications for the mom. ...Read more

For every 10, 000 screened, 100 may show positive & secondary tests will show 2--3 with a real problem. The screen eliminated 99% that didn't need a specific test.The state notifies me of + screens & we get the tests.If a real pbm, rx is atarted. ...Read more

How often is hemolytic disease of the newborn fatal?

Depends on form: Decades ago when i started rh hemolytic disease was often fatal during pregnancy & problamatic in newborns. Surviving infants often needed many exchange transfusions & had worrisome futures. Then a treatment called Rhogam came along & has ended that nightmare. In 26 yrs, I have transfused 1-2 ABO babies primarily for late stage anemia but had no fatalities. Rh disease is a problem without rx. ...Read more

If my 2nd son had hemolytic disease of the newborn, what are the chances the rest of my babies will as well?

If my 2nd son had hemolytic disease of the newborn, what are the chances the rest of my babies will as well?

Depends: Hemolytic disease of the newborn, which is due to rh or ABO incompatibility, happens when the newborn's blood type is incompatible with the mother's, and the mother has passed antibody to the baby in utero. In ABO disease, the mother must be type o and the baby either a or b. In rh disease, the mother must be rh- and the baby rh+. So, subsequent risk depends on the fetus' blood type. ...Read more

Can symptoms of hemolytic disease of the newborn happen a week after birth?

HDN: The process of hemolytic disease of the newborn (HDN) starts soon after birth, however the symptoms (mainly jaundice) may not be detected if clinicians do not maintain a high index of suspicion. HDN due to Rh incompatibility is very rare in the US, but ABO incompatibility should be suspected whenever the mother has type O blood and the baby has either type A or B blood and there jaundice. ...Read more

What are the symptoms associated with hemolytic disease of newborn?

Jaundice and anemia: Hemolytic disease of the newborn (hdn) may develop when a mother and her unborn baby have different blood types. The mother produces substances called antibodies that attack the developing baby's red blood cells. The most common form of hdn is ABO incompatibility, which is usually not very severe. The least common form is rh incompatibility, which can be very severe, but can be prevented. ...Read more

What is the definition or description of: Hemolytic disease of newborn?

HDN: During pregnancy, red blood cells from the unborn baby can cross into the mother's blood through the placenta. Hemolytic Disease of the Newborn occurs when the immune system of the mother sees a baby's red blood cells as foreign and produces antibodies against the baby's red blood cells. These antibodies attack the red blood cells in the baby's blood and cause them to break down too early. ...Read more

How can hemolytic disease be prevented in a newborn?

ABO hemolysis: Hemolysis in newborns due to ABO incompatibility is not preventable, but is manageable under the care of an experienced pediatrician or neonatologist. For this reason, newborns from mothers with type O blood type or who are Rh- will be screened closely for this condition, as early recognition and intervention is key to successful recovery. ...Read more

Whats hemolytic disease of newborn?

Different blood type: Hemolytic disease of newborn is caused by different blood types in mom and baby. Classically, mom is rh negative (a- or o-, etc). The baby is rh positive. Mom then make rh antibodies that cross over to the baby and cause breakdown of the red blood cells. This can make the baby very sick. ...Read more

Can a rh+ baby during pregnancy can lead to hemolytic disease?

Can a rh+ baby during pregnancy can lead to hemolytic disease?

Yes. But only...: Mom would need to be rh negative. This would sensitize the mom, producing an anti-rh antibody that can cross the placenta and began to hemolyze the rh positive cells of the infant. This can began to occur early in the pregnancy, making the unborn child very sick. Or it can be detected at birth and cause prolonged jaundice. Subsequent children may be more affected. Mom needs rhogam. ...Read more
