Aim: The aim of our study is to compare the proteinuria levels measured by dipstick in complete urine analysis at admission with the proteinuria levels measured in 24-hour collected urine for patients hospitalized with a presumptive diagnosis of preeclampsia. By doing so, we intend to review the reliability of the widely used dipstick proteinuria in patients with preeclampsia.
Material ve Metod: Urine specimens were obtained from 70 pregnant women visiting high-risk maternity centers at a third-level healthcare institution. Patients were divided into four groups based on their urine dipstick screening test results: negative, +1, +2, +3, and higher. Proteinuria was considered to be present if the urinary dipstick test showed +1 or higher, while protein levels measured in the 24-hour urine collection were considered to indicate proteinuria if they exceeded 300 mg. The degree of correlation between the urine dipstick test and both 24-hour urine samples and spot urine protein-to-creatinine ratio (Pr/Cr) was compared.
Results: The mean age of the 70 preeclampsia patients in the study group was 31.7±6.2, and the mean gestational age was 32.5±4.6. The dipstick test was found to have a sensitivity of 81.4% and a specificity of 85.2%. The dipstick test results were grouped as 0, +1, +2, +3, and higher. Statistically significant differences were detected among the groups in terms of systolic blood pressure, diastolic blood pressure, the amount of protein in the 24-hour urine, and spot urine Pr/Cr (p=0.001, p<0.001, p<0.001, p<0.001, respectively). When examining the correlation between the urine dipstick test and both 24-hour urine samples and spot urine Pr/Cr, a moderate correlation was found (r=0.65, p<0.001, r=0.55, p<0.001, respectively).
Conclusion: In hypertensive pregnant individuals, urine dipstick tests demonstrated inadequate performance in ruling out preeclampsia. Consequently, according to our investigation, we posit that the dipstick urine test can be employed as a routine and dependable diagnostic tool for preeclampsia due to its rapid results and cost-effectiveness.

Amaç: Çalışmamızın amacı, preeklampsi tanısı ile hastaneye yatırılan hastalarda başvuru sırasında tam idrar analizinde dipstick ile ölçülen proteinüri düzeyleri ile 24 saatlik toplanan idrarda ölçülen proteinüri düzeylerini karşılaştırmaktır. Bunu yaparak, preeklampsili hastalarda yaygın olarak kullanılan dipstick proteinürinin güvenilirliğini gözden geçirmeyi amaçlıyoruz.
Materyal ve Metod: İdrar örnekleri, üçüncü düzey bir sağlık kurumundaki yüksek riskli doğum merkezlerini ziyaret eden 70 hamile kadından elde edilmiştir. Hastalar idrar dipstick tarama testi sonuçlarına göre negatif, +1, +2, +3 ve üzeri olmak üzere dört gruba ayrıldı. İdrar çubuğu testi +1 veya daha yüksek çıkarsa proteinüri var kabul edilirken, 24 saatlik idrar koleksiyonunda ölçülen protein seviyeleri 300 mg'ı aşarsa proteinüri olduğu kabul edildi. İdrar çubuğu testi ile hem 24 saatlik idrar örnekleri hem de spot idrar protein-kreatinin oranı (Pr/Cr) arasındaki korelasyon derecesi karşılaştırılmıştır.Bulgular: Çalışma grubundaki 70 preeklampsi hastasının ortalama yaşı 31.7±6.2 ve ortalama gebelik yaşı 32.5±4.6 idi. Dipstick testinin duyarlılığı %81,4 ve özgüllüğü %85,2 olarak bulundu. Yağ çubuğu testi sonuçları 0, +1, +2, +3 ve üzeri olarak gruplandırıldı. Gruplar arasında sistolik kan basıncı, diyastolik kan basıncı, 24 saatlik idrardaki protein miktarı ve spot idrar Pr/Cr açısından istatistiksel olarak anlamlı farklılıklar tespit edildi (sırasıyla p=0.001, p<0.001, p<0.001, p<0.001). İdrar dipstick testi ile hem 24 saatlik idrar örnekleri hem de spot idrar Pr/Cr arasındaki korelasyon incelendiğinde, orta düzeyde bir korelasyon bulunmuştur (sırasıyla r=0.65, p<0.001, r=0.55, p<0.001).
Sonuç: Hipertansif gebe bireylerde, idrar çubuğu testleri preeklampsiyi ekarte etmede yetersiz performans göstermiştir. Sonuç olarak, araştırmamıza göre, hızlı sonuçları ve maliyet etkinliği nedeniyle dipstick idrar testinin preeklampsi için rutin ve güvenilir bir tanı aracı olarak kullanılabileceğini düşünüyoruz.
