How common is DNA testing in Bangladesh? Primary facts within legal limits
It is not a procedure that can be done randomly or at personal will
DNA (Deoxyribonucleic Acid) testing is a scientific method used to determine biological relationships and identity, and to support criminal investigations. However, it is not an informal or freely accessible procedure as is commonly believed.
In paternity or maternity disputes, DNA testing is generally conducted after the birth of a child, as postnatal samples provide more reliable results.
While advanced medical science allows limited prenatal testing in specific situations, such procedures are not routinely used for determining paternity.

In Bangladesh, the process is governed by strict legal and procedural frameworks to ensure accuracy, reliability, and the protection of individual rights, primarily under the DNA Act 2014, the Code of Criminal Procedure (CrPC) 1898, and relevant provisions of the Evidence Act 1872, according to Advocate Muhammad Hasibur Rahman.
It is not a procedure that can be done randomly or at personal will.
According to the law, DNA testing is carried out under regulated conditions, often requiring the consent of the individual concerned. In criminal investigations or court-directed cases, samples may be collected under lawful authority even without consent.
The collection and handling of DNA samples follow a strict chain of custody to preserve integrity and prevent contamination or tampering.
In the Bangladeshi legal system, DNA analysis is primarily conducted in designated government forensic laboratories, including those under the Criminal Investigation Department (CID), under the authority of the DNA Act 2014.
Once testing is completed, the results are securely documented and submitted to the relevant investigating authority or court.
In ongoing legal proceedings, the findings are presented as forensic evidence and are ultimately assessed by the judiciary during trial.
Throughout the process, confidentiality is strictly maintained, and access to results is tightly controlled to ensure fairness in the justice system.
Overall, DNA testing in Bangladesh operates at the intersection of science and law, playing a vital role in ensuring justice through evidence-based investigation.
