NT scan tu memang bagus untuk detect early risk of down syndrome and chromosomal issues, tapi it's really your choice, ada yang prefer buat for peace of mind, ada yang tunggu detailed scan je nanti sebab risiko depends on age and family history jugak. Kalau you're worried or nak lebih information, best to chat dengan your doctor atau gynae to see if it's recommended untuk your situation, because they know your medical history best, and they can guide you on timing and what makes sense untuk you.
