Abstract

A total of 70% of laboratory test results form the basis for medical decision-making. Approximately 61% of all laboratory errors are caused by pre-analytical procedures, including the length of time the test is delayed. K3EDTA is the anticoagulant used in this study. One important test for making a diagnosis is the assessment of erythrocyte indices. In this study, EDTA blood samples were evaluated immediately and after delays of two, four, and six hours to determine the success rate of erythrocyte index testing (MCV, MCH, and MCHC). This study used an analytical design and observational research methodology. Purposive sampling was used to identify 45 sixth-semester students from the Diploma Three program in Medical Laboratory Technology at the Surabaya Ministry of Health Polytechnic as the research population. This study was conducted in May 2025. The research data consisted of primary data obtained directly from laboratory test results. The data analysis techniques used were the Shapiro-Wilk normality test, homogeneity test, and parametric One-Way ANOVA test. The results of this study showed that delaying the EDTA blood sample examination did not affect the erythrocyte index values, with a success rate of 100%. ABSTRAKSebanyak 70% hasil pemeriksaan laboratorium menjadi dasar dalam pengambilan keputusan medis. Sekitar 61% dari semua kesalahan laboratorium disebabkan oleh prosedur pra-analitik, diantaranya adalah lama waktu penundaan pemeriksaan. K3EDTA adalah antikoagulan yang digunakan dalam penelitian ini. Salah satu tes penting untuk membuat diagnosis adalah penilaian indeks eritrosit. Dalam studi ini, sampel darah EDTA dievaluasi secara langsung dan setelah penundaan dua, empat, dan enam jam untuk menentukan tingkat keberhasilan pemeriksaan indeks eritrosit (MCV, MCH, dan MCHC). Penelitian ini menggunakan desain analitis dan metodologi penelitian observasional. Sampling purposive digunakan untuk mengidentifikasi 45 mahasiswa program Diploma Tiga jurusan Teknologi Laboratorium Medis semester keenam di Politeknik Kesehatan Kementerian Kesehatan Surabaya yang menjadi populasi penelitian. Penelitian ini dilakukan pada bulan Mei 2025. Data penelitian ini berupa data primer yang didapatkan langsung dari hasil pemeriksaan laboratorium. Teknik analisis data yang digunakan adalah uji normalitas menggunakan uji Shapiro-Wilk , uji homogenitas, dan uji parametrik One Away ANOVA. Hasil penelitian ini menunjukkan bahwa penundaan waktu pemeriksaan sampel darah EDTA tidak memengaruhi nilai indeks eritrosit, dengan tingkat keberhasilan mencapai 100%.

Abstract

ABSTRACT Iron deficiency anemia is a common nutritional problem among adolescent girls in developing countries such as Indonesia, affecting both health and academic performance. The government has implemented a school-based iron supplementation program to address this issue. This study aims to evaluate the effectiveness of iron tablet supplementation in increasing hemoglobin levels among 10th-grade female students at MAN 3 Magetan. The study used a quasi-experimental design with a one-group pre-test and post-test approach. A total of 122 students aged 15–18 years participated based on inclusion criteria and parental consent. The intervention involved weekly iron tablet supplementation for three months. Hemoglobin levels were measured before and after the intervention using a HemoCue device, and data were analyzed using the Wilcoxon Signed-Rank test. The results showed a significant increase in hemoglobin levels after the intervention (p < 0.05). Prior to supplementation, 39% of the students were anemic, which decreased to 8% after the intervention, with 92% having normal hemoglobin levels. These findings indicate that regular iron supplementation effectively improves hemoglobin levels and reduces anemia prevalence. The program should be continued with sustained nutrition education and monitoring of compliance to ensure long-term effectiveness. ABSTRAK Anemia defisiensi zat besi merupakan masalah gizi yang umum pada remaja putri di negara berkembang seperti Indonesia, berdampak pada kesehatan dan prestasi belajar. Pemerintah telah menjalankan program pemberian tablet tambah darah (TTD) di sekolah sebagai upaya pencegahan. Penelitian ini bertujuan mengevaluasi efektivitas pemberian TTD terhadap peningkatan kadar hemoglobin pada siswi kelas X di MAN 3 Magetan. Desain penelitian menggunakan kuasi eksperimen dengan pendekatan one group pre-test dan post-test. Sebanyak 122 siswi usia 15–18 tahun menjadi responden berdasarkan kriteria inklusi dan persetujuan orang tua. Intervensi berupa pemberian TTD dilakukan seminggu sekali selama tiga bulan. Kadar hemoglobin diukur sebelum dan sesudah intervensi menggunakan alat HemoCue, dan data dianalisis dengan uji Wilcoxon Signed-Rank. Hasil menunjukkan peningkatan signifikan kadar hemoglobin setelah intervensi (p < 0,05). Sebelum intervensi, 39% siswi mengalami anemia, sementara setelahnya hanya 8%, dengan 92% memiliki kadar hemoglobin normal. Temuan ini menunjukkan bahwa pemberian TTD secara rutin efektif meningkatkan kadar hemoglobin dan menurunkan prevalensi anemia. Program ini perlu dilanjutkan secara berkelanjutan dengan edukasi gizi dan pemantauan kepatuhan konsumsi untuk hasil jangka panjang.
