Fetal lung fluid & pee = amniotic fluid? So how do they get chromosomes?

Exfoliated fetal cel: The amniotic fluid that is contained within the pregnancy sac and surrounds the fetus is fetal urine (after 16-18 weeks) and is swallowed by the fetus and aspirated into its lungs to help them mature. When a doctor performs an amniocentesis to sample this fluid, the goal is to get fetal cells that float in that fluid (exfoliated from various fetal tissues but mainly from the skin) for dna analysis. ...Read more

How are bone marrow biopsy and chromosome analysis different?

How are bone marrow biopsy and chromosome analysis different?

There is big differe: Bone marrow biopsy is done to obtain a pice of tissue to look under the microscope and find out if the blood formation is normal or abnormal. Chromosomes are not visible in the standard bone marrow biopsy. For this we need to culture the blood cells and capture the chromosomes when they are well formed just before the cells divide. This test takes a laboratory which can culture blood cells to see. ...Read more

What are the differences between bone marrow biopsy and chromosome analysis?

Different : A bone marrow biopsy is a sampling of the marrow for a host of diagnostic workups. A chromosome analysis entails looking at the genes and structure within the nucleus of a cell. They may come from the bone marrow if needed. ...Read more

What does an excess of amniotic fluid mean?

Diabetes?: Most of the time we don't know what causes polyhydramnios. It is associated with maternal diabetes and can result from trouble with the fetal kidneys or swallowing ability. In and of itself, it isn't harmful, though it can result in cord prolapse if the water breaks through an open cervix. Ask your doctor. ...Read more

What is a fish test on amniotic fluid?

What is a fish test on amniotic fluid?

Rapid look for Down.: Fish stands of fluorescent in-situ hybidization of the chromosomes in fetal cells obtained after invasive prenatal diagnosis (such as amniocentesis). When time is of the essence, fish can give a preliminary result of fetal aneuploidy (e.g. Down syndrome) within 24 hours from the procedure. It should be followed by a full karyotype and chromosomal microarray analysis. ...Read more
