The Central Bureau of Investigation (CBI) had conducted the tests.
A special Central Bureau of Investigation (CBI) court in Ghaziabad on Sept 30 began hearing the final arguments in the case.
On Sept 28, the court had rejected dentist couple Rajesh and Nupur Talwar's plea to send suspected murder object - a 'khukri' - to a British forensic lab for another round of DNA testing.
The court had fixed Sept 30 for starting the final arguments in the case.
Earlier in June, Talwars, who are accused of killing Aarushi and Hemraj, sought submission of reports of brain mapping test, polygraph test, narco analysis test and psychological test conducted during investigating the case.
Teenager Aarushi Talwar was found dead, with her throat slit, at the Talwar residence in Noida in the morning of May 16, 2008. The body of Hemraj, Talwars' domestic help, was found on the terrace the next day.
The case has since spiralled into one of the country's biggest unsolved cases, with a prolonged investigation marked by admissions of lack of evidence and dramatic twists.
Nupur and Rajesh Talwar maintained that they are innocent, and are being framed by the CBI since the agency has not been able to track down the real killers.
