An essential prenatal test provided by HHD is the HHD Double Marker Test, which measures the likelihood of chromosomal abnormalities in the early stages of pregnancy, including trisomy 18 and Down syndrome. Two particular chemicals in the mother’s blood are measured in this test; these molecules are markers of possible genetic problems. The HHD Double Marker Test gives pregnant parents the information they need to make educated decisions about additional diagnostic testing and care throughout the first trimester. During this crucial period of pregnancy, trust HHD to provide accurate results and compassionate care to safeguard the health and well-being of both mother and child.
