Colombian results of the interlaboratory quality control exercise 2015

Abstract

Currently, all agencies of conformity assessment testing laboratory favor the participation in proficiency testing as a mechanism for quality assurance. In Colombia, the Genes Laboratory has been designated, since 2008, to perform, design and implement proficiency testing for all the interested laboratories. In this report, the results of Colombian exercise Interlaboratory Quality Control for the year 2015 are presented. The exercise consisted of one practical component, one theoretical mandatory component, and an optional theoretical component. Twenty laboratories participated, representing six different countries of Latin America and the Caribbean. For the practical component each participant laboratory received; (1) samples of blood, saliva, and semen stains, in this part they should report the routine own laboratory markers for each sample, (2) three optional theoretical cases of varying complexity, (3) a mandatory theoretical approach about a biological relationship of paternal grandparentsgranddaughter case. In the last two components of the exercise, they had to submit only the calculations. For the practical component the consensus of 70 STR markers, distributed between autosomal and linked to the sex chromosomes, was achieved with an error rate of 0.80% in genotyping, 1.0% nomenclature and/or format discrepancies and 3.8% non-reporting. On the other hand, 99.4% of the reported values were correct, only two values were not correct (0.6%) but were within the range of 5% of the correct value, being acceptable values within the rules of the exercise. This inter-laboratory exercise has become an important mechanism for quality assurance and ongoing training in the region.

Colombian results of the interlaboratory quality control exercise 2013–2014

“…Consensus was established with a minimum of three (3) laboratories with the same genotyping for each marker, therefore the result must match 70% of the laboratories that send results to a marker. For analysis of the results were taken into account the findings from previous years [1,2,3] and the recommendations of both the ISFG [4] and the GHEP-ISFG [5].…”

The Effect of Circuit Games on Increasing the Physical Fitness of Students Aged 8–12 Years

“…The principle of activity in carrying out physical activity carried out by an individual becomes a benchmark forgetting maximum results. In realizing this, an individual really needs the BBTT principle (good, right, measurable and regular) in carrying out various physical activities both individually and in groups [8,9]. The health condition of a student is in the good category, then the student concerned has carried out physical activities according to his best abilities, a student is said to be right, if the student concerned has carried out various physical activities in stages, a student is declared measurable when the student the student concerned has carried out physical activity with the right intensity and time, and Regular means physical activity carried out by a student 3-5 times a week [10,11].…”
