Aim: The aim of this study was to determine the diagnostic accuracy of different urine dipstick protein threshold levels in predicting the presence of abnormal proteinuria in pregnant women with hypertension.
Material and Methods: A total of 326 singleton pregnant women who underwent 501 urine protein tests and who had suspected preeclampsia were included in this retrospective study. Patient data was taken including medical and obstetric history. The results of dipstick urinalysis and concurrent 24-hour urine protein excretion measurements were compared to determine the accuracy of urinalysis.
Results: A dipstick result of 1+ was found to be the best cut-off to predict 500 mg of protein excretion per day, with sensitivity and specificity of 62.09% and 88.97%, respectively. A 2+ proteinuria dipstick cut-off had high specificity and positive predictive value (PPV) (99.05% and 98.84%, respectively) for the prediction of 300 mg of protein excretion per day; this cut-off had low sensitivity (21.46%). A cut-off of 1+ also provided satisfactory specificity and PPV (91.43% and 94.48%, respectively) for the detection of 300 mg of protein excretion per day, but sensitivity was compromised (38.89%). Among 301 patients with negative dipstick results, 212 had a 24-hour urine protein extraction greater than 300 mg, with a false negative rate of 70.43%.
Conclusion: The results suggest that the urine protein dipstick measurement has limited quantitative ability for the prediction of abnormal proteinuria. Additionally, the use of 500 mg 24-hours protein excretion as a cut-off value for abnormal proteinuria may provide useful data.

Amaç: Bu çalışmanın amacı, hipertansif gebelerde anormal proteinüri varlığını öngörmede farklı idrar ölçüm çubuğu protein eşik seviyelerinin tanısal doğruluğunu belirlemektir.
Gereç ve Yöntemler: Bu retrospektif çalışmaya, preeklampsiden şüphelenilen toplam 326 tekiz gebe kadından elde edilen 501 idrar protein testi sonucu dahil edilmiştir. Hastaların tıbbi ve obstetrik geçmiş verileri kaydedildi. İdrar tahlilinin doğruluğunu belirlemek için idrar ölçüm çubuğu protein tahlili ve eşzamanlı 24 saatlik idrar protein atılım ölçümlerinin sonuçları karşılaştırıldı.
Bulgular: 1+ spot idrar protein ölçüm sonucu, 500 mg günlük protein atılımını sırasıyla %62.09 duyarlılık ve %88.97 özgüllük ile öngörmede en iyi kesim değeri olarak bulundu. Spot idrarda 2+ proteinüri değeri; 300 mg günlük protein atılımını öngörmede yüksek özgüllük ve pozitif tahmin değerine (PTD) (sırasıyla %99.05 ve %98.84) sahipken, bu kesim değerinin duyarlılığı düşüktür (%21.46). 1+ kesim değeri; 300 mg günlük protein atılımının saptanması için tatmin edici özgüllük ve pozitif tahmin değerine sahipti (sırasıyla %91.43 ve%94.48), ancak duyarlılığı düşüktü (%38.89). Spot idrar protein ölçümü negatif olan 301 hastadan 212'sinde günlük 300 mg üzeri 24 saatlik idrar protein atılımı tespit edildi (%70,43 yanlış negatiflik).
Sonuç: Sonuçlar, spot idrar protein ölçümünün anormal proteinüriyi tahmin etmek için sınırlı niceliksel kabiliyete sahip olduğunu göstermektedir. Ek olarak, anormal proteinüri için kesme değeri olarak 500 mg 24 saatlik protein atılımının kullanılması yararlı veriler sağlayabilir.
