Blood tests and biological sex:
Chromosomal analysis:
Blood tests can analyze a person's chromosomes (specifically, the X and Y chromosomes) to determine biological sex.
Presence of Y chromosome:
The presence of a Y chromosome indicates biological male (XY), while the absence of a Y chromosome indicates biological female (XX).
Non-invasive prenatal testing (NIPT):
NIPT, which involves analyzing a pregnant woman's blood, can also determine fetal sex by detecting the presence or absence of the Y chromosome.
