  • Pathology and Pregnancy Congratulations As Everyone Will Tell You, Having a Baby Is One of Life’S Most Amazing and Enriching Experiences
    Pathology and Pregnancy Congratulations As everyone will tell you, having a baby is one of life’s most amazing and enriching experiences. Whether this is your first pregnancy or you’ve done it all before, pathology tests will play a vital role in your care and progress. Every pregnancy is different. As your pregnancy progresses and your baby develops, you can expect to have some relevant tests. This booklet sets out the tests and gives you information about what they tell us. Some will be a matter of routine and others may be suggested if your doctor or midwife thinks they are necessary. Some will be done regularly every few weeks, others only at certain times when your baby is at a particular developmental milestone. It’s our job to perform your tests. You are most likely to meet us through our caring and friendly blood collectors. Behind them, back in the lab, are our pathologists and scientists, the medical experts who do the testing and interpret the results. They help your doctor make the important decisions. All of us at Sullivan Nicolaides Pathology are part of your healthcare team, and we are with you every step of the way. We wish you a happy pregnancy and a safe delivery 2 TESTS DURING PREGNANCY Not all tests are routine; some may only be performed if indicated.

  • Pregnancy Testing
    PREGNANCY TESTING I. INTRODUCTION Early pregnancy testing has a number of benefits. A positive pregnancy test allows for early entry into prenatal services for those who wish to be pregnant or a discussion of options for those who do not wish to be pregnant. A negative pregnancy test provides the opportunity to discuss contraception for those who wish not to be pregnant or preconception counseling for those wishing to become pregnant. A number of different pregnancy tests are available. The most common office pregnancy tests are urine immunometric assays that are specific for the Beta subunit of human chorionic gonadotropin (-hCG). These tests provide accurate qualitative (positive or negative) test results for hCG levels from 5 to 50 mIU/mL. Most of these tests can detect pregnancy 7-10 days after conception and approximately 1 week before the next period is due. False-negative results can occur if the urine specimen is dilute or if the -hCG level is too low to be detected by that specific test. False-positive results can occur due to product or laboratory error or due to a cross-reaction of hCG with luteinizing hormone. Urine pregnancy tests do not quantitate the level of -hCG present. The immunometric tests for urinary -hCG are generally positive when the maternal serum levels of -hCG are 25 mIU/mL or more. After delivery or termination of pregnancy, -hCG levels decrease slowly. A - hCG level may be detected in the urine as long as 60 days (31-38 days usual range) after a first trimester abortion. As long as the -hCG levels are dropping this should not cause concern.

  • How Can Genetic Testing Help You with Your IVF Treatment?
    How can genetic testing help you with your IVF treatment? In vitro fertilization, commonly referred to as IVF, is the assisted process of fertilization to help in the conception of a child. IVF utilizes a controlled laboratory environment that can significantly increase the chance of having a baby. With IVF, a sperm and egg are combined, to create an embryo that is incubated and carefully monitored as it begins to grow and develop over the next 5 to 6 days. Embryos that develop suc- cessfully can be transferred back into the uterus or frozen for a future transfer. About 10-12 days after an embryo transfer, the patient will take a pregnancy test. Table of contents Table Why should I start 01 IVF treatment p. 4 What is involved 02 in an IVF cycle? p. 6 Success 03 factors p. 17 Your IVF treatment journey and 04 genetic testing p. 21 About 05 Igenomix p. 35 01 Why should I start IVF treatment? INFERTILITY OTHER REASONS Female ovulation Genetic disorders disorders Blocked, damaged Carrier of genetic or removed disorder fallopian tubes Same sex couples Premature using gamete ovarian failure donors Male infertility Fertility Others preservation 4 In vitro fertilization is typically used when couples have been unable to conceive after trying other types of fertility treatments. IVF can be used to treat infertility caused by a number of reasons, including fema- le ovulation disorders; premature ovarian failure; blocked, damaged or removed fallo- pian tubes; and male infertility. IVF may also be useful for fertile indivi- duals seeking to pursue genetic testing of embryos, or PGT, for a hereditary disor- der, for same-sex couples who wish to use gamete donors, for individuals who re- quire a gestational carrier, or for fertility preservation.

  • V-Safe Pregnancy Surveillance (Amendment)
    V-safe pregnancy surveillance (amendment) CDC Investigators and collaborators: Lakshmi Panagiotakopoulos, Titilope Oduyebo, Paige Marquez, Pedro Moro, Christine Olson, Anne Hause, Naomi Tepper, Dana Meaney Delman, Julianne Gee, Tom Shimabukuro, Tanya Myers, Suzanne Gilboa, Sascha Ellington, and others TBD Protocol amendment summary: V-safe is a novel smartphone-based active vaccine safety surveillance program that will be implemented at the start of an FDA Emergency Use Authorization (EUA) for COVID-19 vaccine use in the United States. As part of this novel public health surveillance activity established for COVID-19, information about pregnancy status at the time of vaccination and at defined follow up time points after vaccination will be collected. This protocol amendment will describe the defined time points and protocol for collecting information about pregnant persons exposed to COVID-19 vaccines and their infants. Given the lack of safety data from pre- EUA clinical trials of COVID-19 vaccines among pregnant persons, the v-safe pregnancy surveillance system will provide critical information to monitor the safety of COVID-19 vaccines administered under EUA and is intended to capture information about pregnant persons and their infants who have been vaccinated. This can inform clinical guidance regarding COVID-19 vaccination during pregnancy and can provide an additional method to detect adverse events that warrant further evaluation using existing safety and database systems. Background: Pregnancy was an exclusion from enrollment in pre-EUA clinical trials for COVID-19 vaccines (www.clinicaltrials.gov). In these pre-EUA clinical trials, pregnancy was screened for and pregnant persons were excluded based on urine pregnancy tests; clinical trial participants were recommended to avoid pregnancy during the trial through the use of reliable and effective contraception.

    The Linacre Quarterly Volume 61 | Number 2 Article 6 May 1994 "New Age" Embryology Text Books: Implications for Fetal Research Dianne N. Irving Follow this and additional works at: https://epublications.marquette.edu/lnq Recommended Citation Irving, Dianne N. (1994) ""New Age" Embryology Text Books: Implications for Fetal Research," The Linacre Quarterly: Vol. 61 : No. 2 , Article 6. Available at: https://epublications.marquette.edu/lnq/vol61/iss2/6 "New Age" Embryology Text Books: Implications for Fetal Research by Dianne N. Irving, M.A., Ph.D. The author is Assistant Professor, History ofPhilosophy/Bioethies at De Sales School of Theology, Washington, D. C. As outrageous as it is that so much incorrect science has been and still is being used in the scientific, medical and bioethics literature to argue that fetal "personhood" does not arrive until some magical biological marker event during human embryological development, now we can witness the "new wave" consequences of passively allowing such incorrect "new age" science to be published and eventually accepted by professionals and non-professionals alike. Once these scientifically erroneous claims, and the erroneoliS philosophical and theological concepts they engender, are successfully imbedded in these bodies of literature and in our collective consciousnesses, the next logical step is to imbed them in our text books, reference materials and federal regulations. Such is the case with the latest fifth edition of a highly respected embryology text book by Keith Moore - The Developing Human. 1 This text is used in most medical schools and graduate biology departments here, and in many institutions abroad. Several definitions and redefinitions of scientific terms it uses are incorporated, it would seem, in order to support the "new age" political agenda of abortion and fetal research.
