Abstract

Kidney failure is the inability of the kidneys to filter blood and maintain electrolyte balance, particularly sodium, which plays an important role in regulating body fluids and neuromuscular activity. Sodium imbalance, such as hyponatremia, often occurs in patients with kidney failure due to impaired excretion, thereby increasing the risk of neurological and cardiovascular complications. This study aimed to compare serum sodium levels between patients with kidney failure and those without kidney failure using the Cornley Electrolyte Analyzer.This research employed a quantitative approach with a cross-sectional design, involving a random sample of 88 respondents (44 patients with kidney failure and 44 without kidney failure) at Al-Ikhlas Islamic Hospital, Pemalang, without considering gender, aged 18–70 years. Serum sodium levels were measured using the ion-selective electrode (ISE) technique. Data analysis included univariate analysis (descriptive statistics and Shapiro-Wilk normality test) and bivariate analysis (Mann-Whitney U test) at a significance level of α=0.05. The results showed that the median serum sodium level in kidney failure patients was 134.5 mmol/L (IQR=9), indicating a higher tendency toward hyponatremia, while non-kidney failure patients had a mean of 137.58 mmol/L (SD=6.70), reflecting greater stability. Statistical analysis demonstrated a significant difference (p=0.014), with higher sodium levels observed in the non-kidney failure group. In conclusion, there is a significant difference in serum sodium levels between the two groups, where patients with kidney failure are more prone to hyponatremia. Therefore, routine electrolyte monitoring and adherence to a low-sodium diet are necessary.

Abstract

Technological advances affect the automation of laboratory equipment, one of which is haemoglobin examination with a haematology analyzer that has several modes of examination to improve accuracy and precision. The haemoglobin test data at RSU Fastabiq Sehat PKU Muhammadiyah Pati reached 25,365 tests. Predilute mode on the Mindray BC-5380 haematology analyser is rarely used, only about 2%, very much different from the use of Whole Blood (WB) mode which reaches a percentage of 98%. This study aims to evaluate the accuracy and precision of the Hematology Analyzer Mindray BC-5380 in Predilute mode for measuring haemoglobin levels using capillary blood at RSU Fastabiq Sehat PKU Muhammadiyah Pati. The methodology used in this study was descriptive quantitative with a cross-sectional approach. Data was obtained through measurement of haemoglobin using the device, which was then analysed to assess accuracy and precision. The results showed a bias value of 2.58%, indicating good accuracy. The coefficient of variation (CV) value of 5.52% exceeded the limit set by the manufacturer, indicating poor precision. Further evaluation using the Levey-Jenning graph and Westgard's rule indicated a 12s deviation on the fifth day, indicating the possibility of systematic or random errors. The Mindray BC-5380 predilute mode haematology analyser had good accuracy of haemoglobin levels in capillary blood, but poor precision compared to the manufacturer's values.

Abstract

This study aims to determine the effect of EDTA blood sample stability on hemoglobin (Hb) and hematocrit (Ht) examination results using an automatic method. EDTA blood samples from 38 employees of Kedung II Public Health Center were examined immediately (0 hours), after a 1-hour delay at room temperature (17–210C), and after a 1-hour delay in a refrigerator (2–80C). The results were analyzed using a Two-Way ANOVA test. The study showed no significant differences in hemoglobin and hematocrit levels between the three storage conditions (ρ > 0.05). The average hemoglobin levels were 12.834 g/dL at 0 hours, 12.797 g/dL after 1 hour at room temperature, and 12.829 g/dL after 1 hour in the refrigerator. The average hematocrit levels were 38.484% at 0 hours, 38.321% after 1 hour at room temperature, and 38.434% after 1 hour in the refrigerator. The conclusion of this study is that storing EDTA blood samples for 1 hour, whether at room temperature or in the refrigerator, does not significantly affect hemoglobin and hematocrit examination results.

Abstract

Pregnant women are one of the populations at risk of contracting Sexually Transmitted Infections (STIs) such as HIV, Syphilis, and Hepatitis B. The prevalence of HIV/AIDS transmission from mother to child is 20-50% where 5-10% occurs during pregnancy. Syphilis transmission is 69-80% and Hepatitis B transmission is more than 90% with the potential for transmission during pregnancy and childbirth being very high. Based on the Regulation of the Minister of Health of the Republic of Indonesia, regulation No. 52 of 2017 concerning the Elimination Program for Transmission of Human Immunodeficiency Virus, Syphilis, and Hepatitis B from Mother to Child or often called "Triple Elimination" aims to stop transmission from mother to child with laboratory examinations on pregnant women at least once during pregnancy. The purpose of this study was to determine the relationship between knowledge and behavior of healthy reproductive age pregnant women in the first trimester at the Lebdosari Health Center. In general, this research method is qualitative with an analytical observational approach and cross-sectional design, namely researchers come and analyze the problem directly. Data collection is carried out at once within a certain time. The population  is pregnant women in the first trimester at the Lebdosari Health Center, with a sample size of 49 people selected based on the Purposive Sampling technique. Data analysis was carried out descriptively and then continued with a bivariate test with the Kendal Tau test because the data was not normally distributed. The results of the study showed that the results of the bivariate test with the Kendal Tau test showed that there was no relationship between knowledge and behavior because the significance value p = 0.888> 0.05 with a positive correlation coefficient value (0.19) which means that there is a positive relationship between knowledge and behavior even though the relationship is weak because the value is less than 1, so that if knowledge increases, behavior will be better. It is recommended that pregnant women are advised to always maintain personal hygiene and implement a clean and healthy lifestyle to prevent infectious diseases.
