Abstract

DIFFERENCES IN HEMOGLOBIN LEVELS IN ANEMIC PATIENTS EXAMINED IMMEDIATELY, AFTER TWO HOURS, AND AFTER THREE HOURS AT SANJIWANI GENERAL HOSPITAL GIANYAR ABSTRACT Background: Delays in blood sample examination can affect the stability of blood components, including hemoglobin levels, thereby influence the accuracy of laboratory results. Objective: To determine the differences in hemoglobin levels in anemic patients examined immediately, delayed for two hours, and three hours at RSUD Sanjiwani Gianyar. Methods: This study used a quasi-experimental design with a repeated measures with purposive sampling approach involving 9 anemic patients. Hemoglobin levels were measured using a hematology analyzer with three examination time treatments: immediate examination, delayed for two hours, and delayed for three hours at room temperature. Data were analyzed using the Shapiro-Wilk test for normality, Repeated Measures ANOVA for comparison, followed by post hoc analysis. Results: The data were normally distributed (p > 0.05). Repeated Measures ANOVA showed a significant difference in hemoglobin levels among the three examination times (p = < 0.05). Pairwise comparisons indicated that all time intervals differed significantly. The mean hemoglobin levels decreased progressively with longer delay. Conclusion: Delays in examination time significantly affect hemoglobin levels, with longer delays resulting in lower hemoglobin values Keywords: Hemoglobin, examination delay, anemia. PERBEDAAN KADAR HEMOGLOBIN PADA PASIEN ANEMIA YANG DIPERIKSA SEGERA, DITUNDA DUA JAM DAN TIGA JAM DI RSUD SANJIWANI GIANYAR ABSTRAK Latar Belakang: Penundaan waktu pemeriksaan sampel darah dapat memengaruhi stabilitas komponen darah, termasuk kadar hemoglobin, sehingga dapat memengaruhi keakuratan hasil laboratorium. Tujuan: Mengetahui perbedaan kadar hemoglobin pada pasien anemia yang diperiksa segera, ditunda dua jam, dan ditunda tiga jam di RSUD Sanjiwani Gianyar. Metode: Penelitian quasi-experimental dengan rancangan repeated measures design dengan purposive sampling pada 9 pasien anemia. Pemeriksaan hemoglobin dilakukan menggunakan hematology analyzer dengan tiga perlakuan waktu pemeriksaan yaitu segera, ditunda dua jam, dan tiga jam pada suhu kamar. Analisis menggunakan uji Shapiro-Wilk, uji Repeated Measures ANOVA dan uji Post Hoc. Hasil: Data berdistribusi normal (p > 0,05). Uji Repeated Measures ANOVA menunjukkan terdapat perbedaan signifikan kadar hemoglobin antar waktu pemeriksaan (p = 0,000 < 0,05). Uji Pairwise Comparisons menunjukkan bahwa semua perbandingan antar waktu pemeriksaan (segera, dua jam, dan tiga jam) memberikan hasil yang bermakna (p < 0,05). Rata-rata kadar hemoglobin mengalami penurunan dari pemeriksaan segera hingga penundaan tiga jam. Simpulan: Terdapat perbedaan signifikan kadar hemoglobin akibat penundaan waktu pemeriksaan. Semakin lama waktu penundaan pemeriksaan, maka kadar hemoglobin semakin menurun. Kata kunci: Hemoglobin, penundaan pemeriksaan, anemia.
