It is usually performed between 11 and 14 weeks of pregnancy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Nuchal Translucency (NT)<\/h3>\n\n\n\n<p>This gauges the amount of fluid in the area behind your baby&#8217;s neck.

Here\u2019s what you can&nbsp;expect during&nbsp;the procedure:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Preparation for the Scan<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>No special preparation is required for the&nbsp;<strong>NT NB scan<\/strong>, but if you have a <strong>moderately full bladder<\/strong> this will improve image clarity.<\/li>\n\n\n\n<li>You must remember that wearing comfortable clothing can make it easy for the healthcare professional to access the abdomen.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. During the Scan<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Most commonly used is a transabdominal ultrasound\u2002(gel is applied on the belly).<\/li>\n\n\n\n<li>A transvaginal ultrasound may be\u2002required to view the IUD in some cases.<\/li>\n\n\n\n<li>The sonographer will measure:<ul><li><strong>Nuchal Translucency (NT) <\/strong>\u2013 the fluid-filled space at the back of the\u2002baby\u2019s neck.<\/li><\/ul>\n<ul class=\"wp-block-list\">\n<li><strong>Nasal Bone (NB):<\/strong> Nasal bone absent or present and development\u2002of the nasal bone.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>The process is\u2002pain-free and lasts for approximately 15\u201330 minutes.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3.

Nuchal Translucency (NT) Measurement<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Normal NT:<\/strong> <strong>Less than 3.0 mm<\/strong> (varies by gestational age).<\/li>\n\n\n\n<li><strong>Increased NT (&gt;3.0 mm):<\/strong> May indicate a higher chance of <strong>Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), or heart defects<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Nasal Bone (NB) Assessment<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Present Nasal Bone:<\/strong> Suggests a lower likelihood of chromosomal abnormalities.<\/li>\n\n\n\n<li><strong>Absent or Underdeveloped Nasal Bone:<\/strong> May be linked to genetic conditions but requires further testing for confirmation.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Combined Risk Assessment<\/h3>\n\n\n\n<p>The NT NB scan is often paired with a <strong>maternal blood test (dual marker test)<\/strong> for a more detailed risk evaluation. The report may indicate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Low Risk:<\/strong> NT and NB appear within expected ranges.<\/li>\n\n\n\n<li><strong>High Risk:<\/strong> Increased NT, absent NB, or abnormal blood test results; further tests like <strong>NIPT, CVS, or amniocentesis<\/strong> may be suggested.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Next Steps<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If the report shows normal values, no additional testing is usually required.<\/li>\n\n\n\n<li>If concerns arise, the doctor may recommend <strong>genetic counselling<\/strong> and more detailed diagnostic tests.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"NT_NB_Scan_Price_in_India\"><\/span>NT NB Scan Price in India<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The average <strong>NT NB scan cost in India<\/strong> varies from diagnostic centers, city to city and type of facility\u2002provided.
