Would-be MBA students getting ready to take the GMAT might be in for a little surprise when they show up at the testing center. In addition to all the usual security measures—including video monitoring and the computer adaptive test itself—test takers will soon be asked to submit to a new one: a biometric device that uses an infared light to capture the test-taker’s unique “palm vein pattern.”

Pearson VUE, the company that administers the GMAT for the Graduate Management Admission Council, plans to announce the new security effort tomorrow, but BusinessWeek got a sneak peak at it today.

The Fujitsu “PalmSecure” device will be rolled out next month at 16 testing centers in India and Korea for GMAT candidates. It goes live in the U.S. this fall, and when fully deployed will be used in 400 facilities in 107 countries by May 2009.

The announcement comes as the b-school world is embroiled in a cheating scandal involving the GMAT–users of a now-defunct test prep Web site, Scoretop.com, have been accused by GMAC of using it to post and access live test questions, and GMAC has said it will cancel the test scores of anyone who violated its rules.

But the new security measure is designed to stop a different kind of cheating–the use of professional test takers, or proxies, to take the exam on behalf of someone else. GMAC’s been burned by this type of cheater before. Back in 2003, it busted a half dozen people who took the GMAT for others for about $5,000 a pop. GMAC canceled 166 scores as a result, and five of the six imposters ended up at Rikers.

Blood Transfusion save millions of lives per year, provided that security of supply can be guaranteed. Unfortunately, the safety of blood and blood components, banks storage leave much to be desired.

More recently, human immunodeficiency virus (HIV) was detected in the blood thalassemic eight children, when they were tested at the School of Tropical Medicine, Kolkata.

The central bank blood in Manicktala found HIV in the blood of another thalassemic five children. Seven children and more with the same passion has been infected with hepatitis C. In all these cases, doctors believe that children have received infected blood during transfusions, the number of thalassemic children, so blood almost twice a month.

Blood transfusion has become one of the diseases most feared forms of contamination. The doctors debt testing and procedure, blood banks of the threat. HIV-Kits, by a majority of blood banks are not enough ensitive for the presence of HIV.

According to doctors, blood banks should begin immediately with the P24-antigen test, as the infection can be detected in blood samples collected in a period of one week after the contraction of the disease. It may however not economically viable government to blood banks.

The Institute of transfusion medicine and blood Immunohaematology IBTI), formerly known as the Central Blood Bank is not capable of introducing P24-test, that the cost of Rs 7000 and polymer chain reaction (PCR ) Test, the best way to detect all types of infections of an astonishing 22000 R sample.

According to the draft National Blood tests for HIV should apply only to laboratories, facilities ELISA. He even hesitate rapid test and use of these centres must be ten per cent of samples to a clinic for the renewal of results.

But most reliable institutions in Calcutta, the School of Tropical Medicine who does not drive ELISA instrument. Neither, he replacement sophisticated machines.

The Institute still too dependent on old machines abroad, were in the sixties. In no other country, these instruments obsolete.

The Blood Transfusion Service in the country is highly decentralized and not of vital resources such as manpower training, infrastructure and adequate financial base. The fragmentation is the management plaguing the blood banking system in the country.

One reason why the blood supply is, is uncertain. The social service organizations tend to organize camps for major events and festivals. Meanwhile, delivery also increases the absorption capacity, but blood cells can not be stockpiled over 35 days. Mistakes storage, there are great opportunities increasingly contaminated blood. The government should take measures to ensure the issuance of permits to all blood banks and gradual occupation of donors.

A Supreme Court, there is in this sense. To ensure that the quality and safety of blood and blood products, well equipped with sufficient infrastructure facilities and personnel necessary. The government should start thinking seriously about the modernisation of blood banks earlier.

The media can also play a role in people more aware that precautionary measures should be taken before the donation and receipt of blood.

In general, it is safe to donate blood, but before the donation, donor countries should ensure that the needle clinics and other materials used must be new and sterile. Before receiving blood, we must check whether HIV, hepatitis B, hepatitis C, VDRL and malaria. Awareness should be among men, so that blood still purchase a license on the organization and preserved blood Pack
