ANSWER: A

• Recently, Supreme Court has said the test can’t be said to be an infallible and cannot be the sole basis to decide the age of an accused who claims to be a juvenile.

• It is the primary test for age determination.
• Human bones are remodelled and new layer of bone material is laid by a process called ossification (or osteogenesis). Based upon this phenomenon, ossification test is carried out.

• This test only tells the ‘estimated’ age of a person and not the exact age.
• The test is not useful when a person has crossed 25-27 years of age. This is primarily because nearly all the bones are completely ossified and the skeletal growth ceases by the age of 25 years.

• Types of SCT
  • Autologous transplantation uses the patient’s own stem cells. These cells are removed, treated and returned to his or her own body after a conditioning regimen.
