Prenatal screening tests & Biometric Identifiers

Biometric Identifiers - Biometric Identification:

What are the benefits of biometrics?

Biometrics potentially provide a more accurate, streamlined and secure method for verifying identity.

Traditionally, identity verification has relied on something you know, such as a password or personal identification number (PIN), or something you have, such as a smart card or access

Biometrics offer the advantage of being based on the unique physical characteristics of an individual. This means there is nothing to carry or remember, and much less possibility that
a biometric identifier could be used without the individual’s knowledge and permission.

Biometric Recognition:

Deoxyribonucleic acid (DNA)

DNA is the genetic blueprint for humans. Everyone except for identical twins has unique DNA. DNA is found in the nucleus of every cell in the body except red blood cells and is the same throughout the body.

There are many regions of DNA molecules that do not hold any known genetic information, but that vary enormously from person to person. These regions are called non-coding or ‘junk’ DNA, and can be used to distinguish between individuals.
