Accuracy Of Measurement Of Hemoglobin Levels With The Portable Hemoglobinometer Method
Accuracy of Measurement of Hemoglobin Levels with the Portable Hemoglobinometer Method
Understanding the Importance of Accurate Hemoglobin Measurement
Anemia is a condition characterized by low hemoglobin levels in the blood, affecting individuals worldwide, regardless of their income level. This disease not only impacts physical health but also interferes with cognitive functions, reduces work performance, and learning, ultimately leading to lower income. According to the Riskesdas 2007 data, 11.3% of women, 12.2% of men, and 12.8% of children in Indonesia suffer from anemia. Globally, the World Health Organization (WHO) data from 1993 to 2005 shows that around 47.4% of preschool children, 41.8% of pregnant women, 30.2% of women who are not pregnant, 25.4% of school-age children, 23.9% of parents, and 12.7% of men experience anemia. Accurate measurement of hemoglobin levels is crucial in diagnosing and managing anemia.
The Need for a Reliable Hemoglobin Measurement Method
Many methods have been developed to measure hemoglobin levels in the blood, but not all of these methods are easy and sensitive in detecting anemia. Therefore, this study aims to evaluate the accuracy of the portable hemoglobinometer method in measuring hemoglobin levels. A reliable and accurate method is essential in healthcare settings, where timely and precise diagnosis is critical.
Research Methods
This research is a diagnostic study with a latitude cut design. The sampling technique used was total sampling, where the total samples were collected as many as 48 people. The study was conducted at the State Elementary School 101747, Klumpang Kebun, Silver Explanatory from March to December 2016. Data analysis was carried out by making a 2x2 table to calculate various parameters, including sensitivity, specificity, positive suspect, negative value, positive possibility ratio, ratio, ratio negative possibilities, as well as compiling ROC curves (Receiver Operating Characteristic).
Research Results
The results showed that the sensitivity value of the portable hemoglobinometer method was 0%, while the specificity reached 100%. The negative alleged value was recorded at 95.8%, the ratio of positive possibilities 0, and the ratio of negative possibilities 1. The area under the ROC curve was 50%, which indicated that only 50% of all tests were made to give correct results, both positive and negative.
Analysis and Discussion
The results showing 100% specificity showed that the portable hemoglobinometer method was very accurate in putting aside the diagnosis of anemia. This means, when the device shows negative results, there is a high certainty that the patient does not experience anemia. However, the low sensitivity value (0%) indicates that this method cannot detect all cases of anemia that exists, so that the potential error in positive diagnosis is very high.
The area under the ROC curve of 50% indicates that the measurement results obtained cannot be fully reliable. In other words, this method is better used to establish a negative diagnosis than positive. This is important to be observed, especially in the context of health services, where the diagnosis of accurate anemia is very necessary to avoid more serious health consequences.
Conclusion
Based on the results of the study, it can be concluded that the portable hemoglobinometer method has a very high specificity in detecting non-anemia, but has significant limitations in detecting cases of anemia itself. Therefore, although this tool can be a practical choice for screening, it should be balanced with other methods that are more sensitive so that the diagnosis of anemia can be done thoroughly and precisely. In the future, further research is needed to develop tools that are not only specific, but also sensitive, for the sake of improving public health.
Implications of the Study
The study highlights the importance of accurate hemoglobin measurement in diagnosing and managing anemia. The portable hemoglobinometer method, although specific, has limitations in detecting cases of anemia. Therefore, healthcare professionals should be aware of these limitations and use this method in conjunction with other methods that are more sensitive. The development of more sensitive and specific tools is crucial in improving public health.
Future Directions
Further research is needed to develop tools that are not only specific but also sensitive. This can be achieved by improving the design and functionality of the portable hemoglobinometer method or by developing new methods that are more accurate and reliable. The development of more accurate and reliable methods will improve the diagnosis and management of anemia, ultimately improving public health.
Recommendations
Healthcare professionals should be aware of the limitations of the portable hemoglobinometer method and use this method in conjunction with other methods that are more sensitive. Patients should also be aware of the importance of accurate hemoglobin measurement in diagnosing and managing anemia. Accurate hemoglobin measurement is crucial in improving public health.
Conclusion
In conclusion, the portable hemoglobinometer method has a very high specificity in detecting non-anemia, but has significant limitations in detecting cases of anemia itself. Therefore, although this tool can be a practical choice for screening, it should be balanced with other methods that are more sensitive so that the diagnosis of anemia can be done thoroughly and precisely. In the future, further research is needed to develop tools that are not only specific, but also sensitive, for the sake of improving public health. Accurate hemoglobin measurement is crucial in improving public health.
