SPECIAL PACKAGE: Those with the above tests done at our clinic will pay $500 less for the Anomaly Scan

safeT21 The Chinese University and Sequenom (USA) technology.

safeT21 is a NIPT originally developed for the screening of Down syndrome.

1. Test performs at or after 9-10 weeks pregnant (Only Panorama can be performed before 10 weeks).

2. Most common trisomies (13, 18 & 21) can be screened (Down Syndrome, Edward & Patau syndromes).

3. Most sex chromosome abnormality (Turner syndrome, Jacob, Klinefelter syndromes).

4. Triploidy can be detected by Panorama test.

5. Microdeletion chromosomal abnormalities: DiGeorge syndrome (22q11.2, prevalence 1 in 1000); 1p36 deletion (Prevalence 1 in 5000); Cri-du-chat syndrome (Prevalence 1 in 20000); Angelman syndrome (Prevalence 1 in 12000) and Prader Willi syndrome (Prevalence 1 in 10000). NIFTY test does not screen for the most common microdeletion (22q11.2). All conditions will affect mental retardation.

6. safeT21 also screens for other microdeletion or chromosomal abnormalities not stated on the above. It offers most comprehensive and thorough screening.

During pregnancy, the unborn child releases some of its DNA into the blood circulation of its mother.  safeT21 is a test that measures the amount of DNA molecules from chromosomes 21, 18 and 13 in the blood sample of the pregnant woman. An abnormally increased amount of chromosome 21 DNA molecules in a pregnant woman’s blood sample is suggestive of Down syndrome. Large-scale clinical studies   have shown that the safeT21 test can detect 99.1% of Down syndrome fetuses. The test has a false-positive rate of 0.1%.Trisomy 18 is associated with abnormally increased amounts of chromosome 18 DNA molecules in the pregnant woman’s blood sample. The safeT21 test can detect >99.9% of trisomy 18 fetuses and has a false-positive rate of 0.4%.Trisomy 13 is associated with abnormally increased amounts of chromosome 13 DNA molecules in the pregnant woman’s blood sample. The test can detect 91.7% of trisomy 13 fetuses and has a false-positive rate of 0.3%. Since there is a chance of false-positive results (meaning that not all positive test results are caused by a fetus with Down syndrome, trisomy 18 or trisomy 13), positive test results should be confirmed by amniocentesis or chorionic villus sampling. On the other hand, a normal result does not fully exclude Down syndrome, trisomy 18 or trisomy 13. It should also be noted that on some occasions, despite all reasonable efforts, results may not be reportable. Such occurrences are rare (0.9% of all test requests) but could be caused by factors such as an unusually low amount of fetal DNA in the blood sample. As part of an effort to continuously improve the performance of the test, the testing laboratory seeks your consent to provide the outcome (e.g. results of amniocentesis or chorionic villus sampling, birth outcome) of your pregnancy, when available, through your obstetrician. Fetal sex related genetic information (e.g. sex chromosome aneuploidies) and other syndromes (e.g. microdeletions related syndromes) are also available.

PANORAMA (performed in united states; current special offer $4500-5500)

http://www.panoramatest.com/

Most people have 23 pairs of chromosomes for a total of 46 — two copies of each set. The Panorama test is highly accurate in screening for instances where there is only one chromosome where there should be a pair, or if there is an extra chromosome, specifically for the chromosomes that are responsible for Down syndrome, Edwards syndrome, Patau syndrome and certain sex chromosome trisomies. Panorama can also identify if there are three sets of each chromosome, which is known as triploidy.

Using single-nucleotide polymorphisms, SNP technology. This test is also being offered at Tsan Yuk Hospital, Lady Helen Woo Women's Diagnostic and Treatment Centre, Hong Kong University.

NIFTY ($4800)
