G: Junior Plan

¥170,000  ( ¥187,000 incl. tax )  
¥214,500for twins, including tax
If you are visiting a related clinic
(¥209,000 including tax)
¥236,500 for twins, incl. tax.

The Junior Plan examines chromosome numbers 13 (Patau Syndrome), 18 (Edwards Syndrome), and 21 (Down Syndrome) which are among the most frequent congenital diseases caused by changes in the number of autosomal chromosomes, which are 22 pairs of chromosomes (44 chromosomes) + partial deletions of all regions of chromosomes 1, 2, 3, 4, 5, 7, 8, 10, 15, 18, 20, 21, and 22. Syndromes will be identified for the three known types. Deletions and duplications in other regions will also be reported.

This plan is recommended by Hiro Clinic NIPT, which has tested over 17,000 people*. (*As of March 11, 2022)

Gender can also be identified.

  • ● Tests abnormalities in Chromosomes 13,18 and 21.

  • ● Tests chromosome 1, 2, 3, 4, 5, 7, 8, 10, 15, 18, 20, 21, 22 whole region for partial deletion and duplication disease abnormalities.


    (Excluding Y)

  • ● For single baby, you will be informed of the sex chromosome abnormalities and gender/sex of the baby.

    Others …
  • ● For twins, we will be informed whether or
    not a Y chromosome is present.


Recommended to:

If you are curious about NIPT but would like to have a comprehensive test.
Those who have experienced repeated miscarriages.
Those who have experienced stillbirths.
This NIPT test is recommended for those who have a close relative with a disability/disorder of some kind.
It is also recommended for those who want to take this opportunity to examine in detail.
This plan is designed based on a study involving over 17,000 pregnant women in Japan to determine the most appropriate test content based on age limitations, target chromosomes, and focus on pregnant women in Japan.

X-linked Recessive Inherited Diseases

The following is a list of the major X-linked recessive inherited diseases/disorders.

Boys may develop the disease/disorder when they have a close relative with X-linked recessive inherited disease/disorder, while girls are often asymptomatic carriers.

Note that NIPT cannot determine the presence or absence of X-linked recessive inherited disease/disorder. However, it is possible to verify the possibility of developing X-linked recessive inherited disease/disorder in a relative by examining the sex of the child.

The following are typical X-linked recessive genetic disorders:

ChromosomeDisease/DisorderOccurrence rate
XX-linked agammaglobulinemia (XLA)Boys 1 in 100,000
XGlucose-6-phosphate dehydrogenase deficiency1 in 1,000
XX-linked hypophosphatemic rickets (XLH)1 in 20,000
Xred-green colorblindness1 in 20 to 500
XHemophilia1 in 4 boys with maternal retention
ChromosomeDisease/DisorderOccurrence rate
XDuchenne muscular dystrophy (DMD)60% for boys 1 in 3,500 maternal retention
XX-linked ichthyosis1 in 2,000 to 6,000
XKallmann syndrome1 in 10,000
X, YLeri-Weill dyschondrosteosis (LWD) 

We recommend that you consider a full-set plan that provides detailed examination to ensure your baby’s safety.

The Junior plan is for the examination of one fetus (single fetus) or twins.
All clinic tests are performed in Japan, and results are usually delivered within 2~5 days (usually within 3~6 days for some clinics and partner clinics) from the time of blood collection. Please note that an express delivery option is available at all Hiro Clinic NIPT clinics (delivery within 2~3 days of blood collection), except for partner clinics.
