Aspiration pneumonia refers to pneumonia caused by accidental inhalation (aspiration) of food, drink, or vomit into the lungs. Swallowing difficulties, or conditions such as alcohol intoxication, confusion, or decreased mental alertness, may lead to aspiration pneumonia.
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.
A karyotype allows scientists to look at the number and structure of the chromosomes on a large scale. 1  The chromosomes can be counted to detect if there is a whole extra chromosome (trisomy) or a whole missing chromosome (monosomy).
