The Turnaround time of analyses results is defined as the delay from biological prescription to the results delivery. The medical decision often depends on the results of biological tests. The purpose of this study is to analyse quantitatively the delay of the results delivery period of the biochemical tests which are urgently requested. It is a prospective and descriptive study on a period of a whole week done in Paraclinical Training and Biochemistry Research Unit of the Joseph Ravoahangy Andrianavalona University Hospital Center during the period of the on- call duty. A total of 129 files were recorded. The delay of the delivery of average results is 295 minutes with extremes of 35 and 368 minutes. The majority of requests contains 3 parameters per request. Many causes of the delay of the results are identified in this study such as the lack of staff in care services and at the laboratory, a long analysis circuit, the absence of automation of the pre and post analytic stages within our laboratory.
Heavy metals resistant bacteria were obtained from wastewater samples in mining sites of Itogon, Benguet, Philippines. The isolates were cultured in a medium with different concentrations of copper (Cu), chromium (Cr), nickel (Ni), zinc (Zn) and lead (Pb). Out of the 150 initial isolates, the 4 isolates, which survived in each 100 ppm of Zn, Cr, Pb, and Ni exhibited high metal resistance and were identified at the Philippine Genome Center (UP Diliman, Quezon City, Philippines) as isolates A). Acinetobacter sp. junii, B). Acinetobacter sp. tandoii, C). Bacillus cereus, D). Bacillus toyonensis. Sample digestion with HCl showed higher heavy metal reduction results compared with the undigested, thus suggesting that acid treatment gave better extraction of metal components prior to Atomic Absorption Spectroscopy. Biosorption of heavy metals were highest in 75 ppm of lead. Results showed that the isolate Bacillus toyonensis can reduce lead by 92.43 % in 5 days at room temperature.
