Replacing abdominal palpation with symphysis-fundal height SFH measurement for the assessment of fetal growth is not recommended to improve perinatal outcomes. A change from what is usually practiced abdominal palpation or SFH measurement in a particular setting is not recommended. SFH measurement is a commonly-practiced method of fetal growth assessment that uses a tape measure to measure the SFH, in order to detect intrauterine growth restriction IUGR. It also has the potential to detect multiple pregnancy, macrosomia, polyhydramnios and oligohydramnios. For fetuses growing normally, from 24 weeks of gestation, the SFH measurement in centimetres should correspond to the number of weeks of gestation, with an allowance of a 2-cm difference either way Other methods of fetal growth assessment include abdominal palpation of fundal height in relation to anatomical landmarks such as the umbilicus and xiphisternum, abdominal girth measurement, and serial ultrasound measurement of the fetal parameters Accurate low-cost methods for detecting abnormal growth are desirable because ultrasound, the most accurate screening tool, is resource-intensive and not widely available in LMICs.

This Signature Article focuses on the evidence on inducing for due dates. The researchers asked mothers to select the reasons that they were induced. In the U. But that number is probably low. In general, inductions are considered medically indicated when there are accepted medical problems or pregnancy complications that make it less safe to continue the pregnancy. Elective inductions might occur for social reasons, like the provider wanting the birth to happen before he or she goes out of town, or other non-medical reasons like the mother wanting to be done with an uncomfortable pregnancy.
ACOG Issues New Prenatal Testing Guidelines
Aetna considers ultrasounds not medically necessary if done solely to determine the fetal sex or to provide parents with a view and photograph of the fetus. Aetna considers detailed ultrasound fetal anatomic examination experimental and investigational for all other indications including routine evaluation of pregnant women who are on bupropion Wellbutrin or levetiracetam Keppra , pregnant women with low pregnancy-associated plasma protein A, and pregnant women who smoke or abuse cannabis.
There is inadequate evidence of the clinical utility of detailed ultrasound fetal anatomic examination for indications other than evaluation of suspected fetal anatomic abnormalities. Detailed ultrasound fetal anatomic examination is not considered medically necessary for routine screening of normal pregnancy, or in the setting of maternal idiopathic pulmonary hemosiderosis.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. This document provides guidance for managing pregnancies in which the best clinical estimate of gestational age is suboptimal.
There is no role for elective delivery in a woman with a suboptimally dated pregnancy. Although guidelines for indicated late-preterm and early-term deliveries depend on accurate determination of gestational age, women with suboptimally dated pregnancies should be managed according to these same guidelines because of the lack of a superior alternative. The best clinical estimate of gestational age should serve as the basis for decisions regarding antenatal corticosteroid exposure in women with suboptimally dated pregnancies who are at perceived risk of preterm delivery.
Amniocentesis for fetal lung maturity is not recommended as a routine component of decision making when considering delivery in a woman with a suboptimally dated pregnancy. Late-term delivery is indicated at 41 weeks of gestation when gestational age is uncertain, using the best clinical estimate of gestational age. Initiation of antepartum fetal surveillance at 39—40 weeks of gestation may be considered for suboptimally dated pregnancies.

Redating a pregnancy may occur when there is a discrepancy between the estimated due date EDD calculated by the last menstrual period LMP and that by ultrasound. Care should be taken when redating a pregnancy, especially in the third trimester, as there may be other reasons for a fetus to be small for gestational age e. According to the ACOG redating is more reliable using the earliest available and reliable ultrasound examination surrogates.
For instance, CRL in the first trimester would be more accurate than a debatable uncertain LMP or 2nd-trimester biometrics.

Truthfully, medical apps are a critical component of my iPhone brand loyalty…. There are seemingly 1 million of them on the app store and every single one seems to give you a different date for some reason, it literally boggled my mind when I first started practicing. With over 6 million pregnancies in the U. I mean, was the year that they published their landmark Commitee Opinion that standardized the calculation of due dates for women everywhere, so a calculator seemed like the next logical step.
What were those dreams, you ask? Keep reading! Ok, given my rant above, you may be asking yourself why it really matters if the due date is off by a day or two. And no.

The most recent revision of these standards occurred in Changes in the clinical standards of prenatal care since that time necessitate a review of Part In order to accomplish this task, the Department partnered with the Island Peer Review Organization IPRO to review the existing PCAP standards and compare them to current American College of Obstetricians and Gynecologists ACOG guidelines 1 new recommendations in prenatal care, as well as other national guidelines of obstetric practice to determine the need to modify the prenatal standards as they become applied to all Medicaid prenatal providers.

You can use the calculator below to calculate the doubling time of two beta hCG samples by entering the date of the blood test and the corresponding beta hCG value for that day. If the hCG level is decreasing the the half life will be calculated. To calculate the doubling time of two beta hCG samples: 1.
Enter the date the first blood test was drawn and the beta HCG value for the date the sample was drawn 2. Enter the date the second blood test was drawn and the beta HCG value for the date the sample was drawn. Ultrasonography is the preferred method to verify the presence of a viable intrauterine gestation. If a woman has a positive urine or serum pregnancy test and no intrauterine or ectopic pregnancy is seen on transvaginal ultrasound she is considered to have a pregnancy of unknown location which may be an early viable intrauterine pregnancy, nonviable intrauterine pregnancy, or ectopic pregnancy.
The hCG value above which an intrauterine gestational sac would first be expected to be seen on ultrasonography in a normal pregnancy is called the discriminatory hCG level . In the presence of an empty uterus the likelihood of a viable pregnancy decreases as the hCG level increases. At an hCG level of more than mIU per milliliter, 0. The discrimantory hCG level has great variability due to hCG assay techniques , quality of ultrasound, and operator experience.
In addition, multiple gestations will have hCG levels considerably higher than singleton gestation before ultrasound findings become visible. Although various hCG discriminatory levels have been used to assess the risk of ectopic pregnancy, there is no established hCG level that is diagnostic of an ectopic pregnancy [2, 4, 5]. A slower rate of increase suggests a possible miscarriage or ectopic pregnancy.

An average pregnancy lasts days from the first day of the last menstrual period LMP or days after conception. It is prudent of the obstetrician to get a detailed menstrual history including duration, flow, previous menstrual periods, and use of hormonal contraceptive.
