WebWhat does a negative or normal chromosomal microarray (aCGH) result mean? A negative result means that the chromosomal microarray test did not detect a significant deletion or duplication in the chromosomes of the fetus. Most individuals have several very small deletions and duplications that are seen frequently and are felt to be normal. WebIn this section we discuss the background knowledge you will need when deciding whether to order chromosomal microarray, including how the test works, what it detects, and when it has proven useful. Below are key questions you should understand before deciding to test with chromosomal microarray. Applying Results. CMA Ordering.
WebHow does array CGH work? A microarray works by exploiting the ability of a DNA molecule (or strand) to bind specifically to, or hybridise to, another DNA molecule (strand). The DNA in our cells is arranged as a double helix (see Figure 2) in which the two strands of DNA are bound (‘paired’) together by bonds between the base pairs (bps).
