Abstract

Turnaround Time (TAT) is an important indicator of laboratory service quality that supports accurate diagnosis and clinical decision-making. Delays in laboratory results may be influenced by pre-analytical, analytical, and post-analytical phases. This study aimed to analyze the factors influencing laboratory Turnaround Time (TAT) at Grandmed Hospital Lubuk Pakam. This study used a quantitative approach with an analytical observational design and a cross-sectional method. The population consisted of 32 clinical laboratory personnel selected using total sampling. Data were collected through validated and reliable questionnaires and secondary data from laboratory information system records. Data were analyzed using univariate and bivariate analysis with Spearman’s rank correlation test at a 95% confidence level. The results showed that most TAT values met the standard (87.5%). The average TAT for emergency services was 87 minutes, outpatient services 118 minutes, and inpatient services 130 minutes, all within the minimum service standard (≤140 minutes). Pre-analytical factors (r = 0.604; p = 0.000) and analytical factors (r = 0.545; p = 0.001) had significant effects on TAT, while post-analytical factors were not significant (r = -0.098; p = 0.595). In conclusion, pre-analytical and analytical factors are the main determinants of TAT, indicating the need to improve these stages to enhance laboratory service quality.

Abstract

Background: Cervical cancer is one of the second-highest sexually transmitted diseases in the world, accounting for 13% of the total 22% of deaths caused by non-communicable diseases. Today there have been many developments about cervical cancer diagnosis methods especially in early detection aimed at recognizing cervical cancer at an earlier stage, including molecular biology detection using PCR tools and electrophoresis. Objective: To identify the results of DNA electrophoresis in vaginal mucosal swabs with cervical cancer. Method : The research method used is experimental. Results: Based on the results of a study using a documentary gel, 2 samples of HPV DNA tape were detected, it was tested positive because there was 450 bp DNA tape and 4 samples of negative results were obtained. Conclusion: The frequency distribution of respondents from 6 samples by using electrophoresis and focumerary gel as readers detected 2 positive samples. A positive result is expressed if a result in the documentary gel is found to be a DNA band. The size of the DNA ribbon produced with the DNA marker markers is at 450 bp, according to the sample target. This shows that the DNA bands in the sample are about 450 bp in size.
