PETALING JAYA: The Malaysian Association of Private Medical Laboratories (MAPML) has disputed the claim of the Consumer Association of Penang (CAP) that medical tests are highly inaccurate.
Its president I.K. Yeo said several factors had to be considered before any deduction could be made on the results of tests on samples at private laboratories.
He said among them were whether the samples were taken at one go or more than once from the person, how it was distributed into five bottles and sent to five different laboratories, its handling, storage and transportation to the laboratories and the equipment and methodology used.
He said the variations were inherent and accepted.
“Any variation in treating the five bottles like excessive shaking, subjecting them to varying temperatures at any stage or taking a longer time to deliver a particular set to a laboratory would contribute to variations of the results,” he said, adding that blood and urine samples are quite unstable and would deteriorate quickly in the tropical climate.
