Abstract

Background: Acute heart disease is among the ten most common non-communicable diseases in Indonesia. Diagnosis of acute heart disease is commonly confirmed using electrocardiography (ECG) or troponin measurement; however, these diagnostic tools are not available in all healthcare facilities. The Neutrophil-to-Lymphocyte Ratio (NLR) is a readily accessible laboratory parameter that can be assessed in patients presenting with chest pain. Purpose: This study aimed to determine the relationship between NLR and High-Sensitivity Troponin I (hs-TnI) levels in patients with acute heart disease who need rapid treatment. Method: This descriptive quantitative study used secondary data obtained from Husada Utama Hospital, Surabaya, covering the period from January 2023 to March 2024. A total of 52 patient records that met the inclusion criteria were analyzed. Statistical analysis was performed using the Spearman correlation test. Result: The findings of this study demonstrated a positive correlation between NLR and hs-TnI levels in patients with acute heart disease at RSUD Husada Utama Surabaya, indicating that an increase in troponin I levels was accompanied by an increase in NLR levels. The majority of patients with acute heart disease are 16 men with a range of ages 46 - 55 years. Data analysis using the Spearman test obtained a correlation coefficient of 0.279, indicating the level of strength of the relationship between variables and a significance value of 0.045 <0.05. Conclusion: There is a significant correlation between NLR and hs-TnI levels in acute heart disease at Husada Utama Hospital, Surabaya.

Abstract

Background: The Jaffe method is still applied with semi-automated analyzers based on picric acid reaction in many laboratories, whereas the enzymatic method is more frequently used as a reference in primary laboratories and hospitals. Purpose: To evaluate the accuracy of the Jaffe method in comparison with the enzymatic method and to assess its precision in measuring normal and abnormally high serum creatinine levels under routine laboratory conditions. Method: The study employed an analytical observational manner at the East Java Province Hajj Hospital and Bakti Analysa Laboratory. Serum samples were obtained from 30 patients with normal creatinine levels and 25 pre-dialysis patients with abnormally high creatinine levels. Accuracy was evaluated by comparing the results of the Jaffe method with those obtained using the enzymatic method, while precision was assessed by repeating the measurements 10 times for each sample. Result: The inaccuracy of the Jaffe method for normal creatinine levels was 19.20%, while for abnormally high creatinine levels, it was -9.33%. The precision value (coefficient of variation) for normal creatinine levels was 5.86%, whereas for abnormally high creatinine levels, it was 1.13%. Conclusion: The Jaffe method for measuring normal creatinine levels demonstrated poor accuracy because the inaccuracy value exceeded the ±10% limit. In contrast, the measurement of abnormally high creatinine levels showed good accuracy because the inaccuracy value remained within the ±10% range. Both normal and abnormally high creatinine measurements using the Jaffe method demonstrated good precision, as the coefficient of variation values were lower than the maximum CV limit of 6%.

Abstract

At the beginning of the Corona Virus Disease 2019 (COVID-19) pandemic, rapid test examinations were widely used as a screening for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. The purpose of this examination was to detect SARS-CoV-2 IgM/IgG antibodies in the patient's body. One of these tests uses the immunochromatographic method. This study aims to determine the validity of immunochromatography. The study was conducted from August to September 2020. The sample used in this study was 100 patients. The research was conducted at Husada Utama Hospital Surabaya, Indonesia. According to the study's findings, the Zybio brand reagent kit has an accuracy of 85%, a sensitivity of 82%, a specificity of 88%, a positive predictive value of 87%, and a negative predictive value of 83%. In the group of patients who experienced clinical symptoms, < 7 had a sensitivity of 50%, specificity of 88%, positive predictive value of 60%, negative predictive value of 83%, and accuracy of 77.94% while the group of patients experiencing clinical symptoms > 7 days, had a sensitivity value of 100 %, specificity of 88%, positive predictive value of 84%, negative predictive value of 100%, and accuracy of 92.68%. Based on these results, the conclusion is that the Zybio brand reagent kit has a relatively high sensitivity, specificity, positive predictive value, negative value, and sample accuracy. In the group with clinical sensitivity < 7 days, the positive predictive value and accuracy are lower than the sample group with clinical symptoms > 7 days but have the same specificity.
