Thalassemia (abbreviated as thalassemia), also known as globin production disorder anemia, is a group of inherited hemolytic anemia diseases. Anemia or pathological condition caused by lack or insufficiency of synthesis of one or more globin chains in hemoglobin due to inherited genetic defects. According to the "Chinese Thalassaemia Blue Book (2015)", there are about 300,000 people with heavy and intermediate thalassaemia in China, and the "thalassaemia" gene carrier exceeds 30 million, involving nearly 30 million families and 100 million people, mainly concentrated in To the south of the Yangtze River, especially in Guangxi and Yunnan, the most severe. Therefore, medical advice is to conduct pre-marital examination and prenatal genetic diagnosis to avoid the occurrence of the next generation of children.

  The thalassemia gene detection kit of 100 million cubic meters covers Thai type, 30M site and -50M site. The overall mutation site coverage rate is more than 95%, which can effectively prevent missed detection.
