Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried about it affecting my fertility, and I'm also extremely sensitive to cold and coldness. How is a chromosome test performed?Doctor's answer:
Hello, cells are fixed on slides using methanol and acetic acid, and their chromosome structure and number are observed under a microscope. The karyotype of a normal male consists of 44 autosomes plus 2 sex chromosomes, X and Y, which is commonly represented as 46,XY in reports. A normal female has the same autosomes as males but 2 sex chromosomes, XX, commonly represented as 46,XX. The number "46" indicates the total number of chromosomes, and any number greater than or less than 46 is considered a chromosomal number abnormality. A missing sex chromosome is commonly represented as O.
