Tarama testi olarak gebelerde glikoz screening uygulaması

Aralık 1998 ile Aralık 1999 tarihleri arasında polikliniğe başvuran 24. Gebelik haftasını aşmış 825 gebeye Gestasyonel diabet sıklığını ortaya çıkarmak amacı ile 50 gr'lık glikoz tarama testi uyguladık. 135 mg/dl üzerindeki test değerlerine Oral Glikoz Tolerans Testi (OGTT) uyguladık. Pozitif screening test oranımız % 4.965 pozitif OGTT oranımız ise % 1.212 düzeyinde gerçekleşti. Eşik değer olarak 140 mg/dl seçildiğinde testin spesifitesi %99'a sensivitesi % 100'e pozitif prediktif değeri ise % 62'ye yükseldi. Yaş parite ve tokluk durumunun testin sonucunu değiştirmediği gözlendi. Bu nedenle 24. Gebelik haftasını geçen tüm gebelere 50 gr glikoz tarama testi uygulanması güvenli ve kolay uygulanabilir bir yöntem olarak kabul edildi.

Glucose challenge test as a screening method in pregnancy

We have studied 50 gr -1 hour glucose screening test to diagnose gestational diabetes mellitus incidence in our clinics between 01.01.99-01.12.99. Screening test was given to 825 gravid women. All women were screened at 24 weeks and above. 4.969 % were found positive for screening test and 1.212 % were to be diabetic. If threshold was chosen as 140 mg/dl, specifity of the test was 99% and sensitivity was 100 %. Positive predictive value was found 62 % also. There were no association between the test values and age, parity or fasting state. We recommend all pregnant women should be screened at 24 week and then for gestational diabetes mellitus. We found this procedure easy to perform, economic and efficient.
