Abstract
Pemantapan Mutu Internal (PMI) memiliki peran penting dalam penjaminan
mutu laboratorium salah satu pendekatan yang digunakan untuk mengevaluasi
kualitas hasil pemeriksaan adalah dengan penerapan aturan Westgard, yang
memungkinkan deteksi dini terhadap kesalahan analitik, baik sistematik maupun
acak. Penelitian ini bertujuan untuk menganalisis hasil Pemantapan Mutu Internal
(PMI) pemeriksaan kolesterol dan glukosa berdasarkan aturan Westgard pada alat
Clinical Chemistry Analyzer TMS 30i di Rumah Sakit Umum Daerah Ir. Soekarno
Sukoharjo.
Metode yang digunakan adalah deskriptif kuantitatif dengan pendekatan
cross-sectional. Evaluasi akurasi dilakukan melalui perhitungan nilai bias,
sementara presisi dianalisis menggunakan Coefficient of Variation (CV%). Hasil
penelitian menunjukkan bahwa nilai CV untuk pemeriksaan kolesterol ≤6% dan
glukosa ≤5%, yang masih berada dalam batas toleransi sesuai standar, sehingga alat
memiliki ketelitian yang baik. Nilai bias juga berada dalam rentang ±10%, yang
menunjukkan akurasi pengukuran yang tinggi.
Kesimpulan dari penelitian ini berdasarkan evaluasi dengan menggunakan
aturan Westgard ditemukan pelanggaran aturan 10x pada kontrol kolesterol serta
pelanggaran 10x, dan 4-1spada kontrol glukosa , yang mengindikasikan adanya
kesalahan sistematik.
Internal Quality Control (IQC) plays an important role in laboratory quality
assurance. One approach used to evaluate the quality of test results is the application
of the Westgard rules, which enable early detection of analytical errors, both
systematic and random. This study aims to analyze the results of Internal Quality
Control (IQC) for cholesterol and glucose testing based on the Westgard rules on
the Clinical Chemistry Analyzer TMS 30i device at the Ir. Soekarno Sukoharjo
Regional General Hospital.
The method used was quantitative descriptive with a cross-sectional
approach. Accuracy was evaluated by calculating the bias value, while precision
was analyzed using the Coefficient of Variation (CV%). The results showed that the
CV value for cholesterol testing was ≤6% and for glucose testing was ≤5%, which
is still within the tolerance limit according to the standard, indicating that the device
has good accuracy. The bias value was also within the range of ±10%, indicating
high measurement accuracy.
The conclusion of this study based on evaluation using Westgard rules found
a 10x rule violation in cholesterol control and 10x and 4-1s violations in glucose
control, indicating systematic errors.
