The Due Date Calculator for Pregnant Patients, also known as the Ultrasound Estimated Gestational Age Calculator, is a clinical tool specifically designed for use in the obstetric population. This calculator is utilized to estimate the due date or expected date of delivery (EDD) of a pregnant patient based on the gestational age determined through ultrasound measurements. 

The clinical utility of this calculator lies in its ability to provide an accurate estimation of the gestational age and subsequently, the due date. This information is crucial for monitoring fetal development, planning appropriate prenatal care, and preparing for delivery. 

The Due Date Calculator for Pregnant Patients is applicable to all pregnant women who have undergone an ultrasound scan. However, it may not provide accurate results in cases where the gestational age is incorrectly estimated due to factors such as fetal anomalies, multiple pregnancies, or errors in ultrasound measurements. Therefore, it should be used in conjunction with other clinical information and diagnostic tools for comprehensive prenatal care.

The Due Date Calculator for Pregnant Patients, often referred to as the Last Menstrual Period (LMP) Calculator, is specifically designed to estimate the expected date of delivery (EDD) or "due date" based on the first day of a woman's last menstrual period. This is a critical aspect of prenatal care, as it helps clinicians to monitor fetal development, schedule appropriate prenatal tests, and anticipate potential complications. 

The LMP calculator assumes a standard 28-day menstrual cycle and that ovulation occurs on day 14. Therefore, it may not be accurate for women with irregular cycles, those who cannot recall the first day of their last menstrual period, or those who conceived while using contraceptive methods that suppress menstruation. Additionally, it may not be applicable for pregnancies resulting from assisted reproductive technologies such as in-vitro fertilization, where the date of conception is known. In such cases, alternative methods of estimating the due date may be more appropriate.
