Labor admission test (LAT) is performed at the onset of labor to establish fetal well-being in low-risk pregnancies and identify those fetuses who either may be hypoxic, needing delivery or at risk of developing hypoxia during labor so that additional measures of fetal surveillance can be instituted to prevent adverse outcomes. We searched the literature in Medline, Cochrane Library and PubMed using the words-cardiotocograph, cardiotocogram, nonstress test, vibroacoustic stimulus (VAS), amniotic fluid index (AFI), Doppler, labor admission test, labor admission cardiotocography (CTG) and reviewed four randomized controlled trials (RCTs) and three systematic reviews to summarize the current evidence regarding use of LAT. Although the existing RCTs and systematic reviews do not favor admission testing, we have critically reviewed the methodology used in some of these major studies. There is a need for robust RCTs with adequate sample size to evaluate the effectiveness of LAT. In clinical practice, while a normal admission CTG reassures the mother and the clinician about the health of the baby, an admission CTG with nonreassuring FHR pattern leads to careful review which may reveal a growth restricted or compromised fetus before onset of active labor when the risk of fetal hypoxia is higher with increasing frequency and duration of uterine contractions. Like in other obstetric interventions, the woman should be offered the choice of LAT after providing appropriate information and her informed decision should be respected.
