Abstract

Background: Gestational
Diabetes Mellitus (GDM) is defined as the glucose intolerance started or
diagnosed first at pregnancy. GDM screening tests are applied as single or
two-step tests. The aim of the present study is to evaluate the numbers and
positiveness ratios of single or two-step screening tests.

Materials and Methods:
The number of GDM screening test pregnant women applied to Ankara Numune
training and Research Hospital Biochemistry Clinic between years 2010-2014 were
evaluated from Hospital Laboratory Information System retrospectively, and
applied numbers of one and two step screening tests and positiveness ratios
were evalauted fort his 5 year period.

Results:
281 (18,5%) of the total 1514 tests were positive. 270 (96,1%) of this positive
results were obtained by one-step test and 11 (3,9%) of them were obtained by
two-step test. In year 2011, all screening tests were carried out by one-step
approach. In years 2012-2014, single step approach was appplied in increasing
ratios. GDM detection rate of sinle-step test was found to be higher than
two-step test.










Conclusion:
Single step approach can be the test of choice for GDM screening as it has a
higher detection rate and more comfortable fort he patient.
