Abstract
It is very important to analyze human chromosomes for the definitive diagnosis, in order to predict congenital abnormality and to prenatally diagnose genetic abnormality of fetuses. This analysis generally has been carried out by well-trained experts with a long-term experience. Since there is a shortage of those experts in the recent clinical field due to the increasing of the diagnosis required chromosomal analyses, it is mandatory to employ more experts. However, it is required that the experts must supervise unskilled trainees to practice to be trained experts despite this circumstance. To increase the number of the experts with a limited time, we therefore developed a new self-training education system for learning the karyotyping skill. This system can improve trainees' skills with their own paces and levels of the skills without supervising by the experts. To evaluate this system, here we tested the performance of how beginners can improve their skill by using this system. Results showed that all trainees could improve their karyotyping skills significantly after 60 repeats of the training. This result indicates that this system has a great performance to learn and to improve the karyotyping skill for any beginners.
