Chromosomal Microarray Analysis of Amniotic Fluid (Cyto-80+) - 華聯生物科技

Chromosomal Microarray Analysis of Amniotic Fluid (Cyto-80+)

Specifically designed for Asians, Phalanx Biotech’s clinical chromosome microarray is used for 80+ disorders of higher incidence, including developmental delay and intellectual disorder, with 500~1000x resolution when compared to conventional options.

Younger mothers should also watch out for chromosomal disorders

With the advancement of gene test technology, scientists found that copy number variation (CNV) is the cause of hundreds of hereditary disorders. Conventional amniotic test (karyotyping) only reveals part of the hereditary risks.

CNV is an all-age risk, and not just seen in geriatric pregnancy! In a joint statement by American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM), it is recommended to use chromosome microarray as a prenatal diagnostic tool and promote it for pregnancies of all age groups.

Common clinical symptoms of CNV
  • Delayed growth
  • Fetal development delay
  • Intellectual development disorder
  • learning disorder
  • Neurological development disorder
  • Motor disorder
  • Dystonia
  • Cardiovascular developmental disorder
  • Facial feature developmental disorder
  • Other congenital developmental disorder

Disease detection

Phalanx Biotech’s chromosome microarrays can be used for the screening of aneuploidy such as Down syndrome and a total of 80+ disorders. Specifically focused on developmental delay and intellectual disability, for example, Down syndrome, Turner syndrome, Edwards syndrome, hemophilia A/B, forebrain defects, obesity, Prader-Willi syndrome, Angelman syndrome, DiGeorge’s syndrome, Cri du chat syndrome, 1p36 deletion syndrome, Patau syndrome, and other disorders associated with chromosomal microdeletion and microamplification. 

The only high-density microarray manufacturer in Asia

Positioned as the only Asian manufacturer with independent microarray design and development capabilities, Phalanx Biotech is also a market leader in terms of technology and quality.

Screening of 80+ selected disorders at affordable price

Probe designed for specific disorders, realizing accurate clinical interpretation at a third to half of the price of conventional microarrays

Microarrays tailored for Asian genes

In collaboration with Taiwanese genetics specialists and clinicians, Phalanx Biotech creates the chromosome microarray tailored for Taiwanese.

Elected as a biotech company with cutting edge technology

Phalanx Biotech’s chromosome technology and quality is internationally acknowledged as demonstrated by being elected as one of the five biotech companies with cutting edge technology, and a dedicated display by Discovery.
