00:00:00 – 00:37:31
The video delves into the advancements in genetic testing, particularly focusing on whole genome sequencing, pharmacogenomic testing, non-invasive prenatal testing (NIPT), and cell-free DNA testing to diagnose genetic conditions and fetal antigens. Topics include the importance of early RH type testing in pregnancy, monitoring for fetal anemia, and the significance of accurate genotyping for personalized care. The video stresses the role of genetic counseling, the need for proactive testing, and the benefits of efficient tests like the Unity blood test for quick and precise medical decisions. The importance of avoiding blood mixing, utilizing confident information for management decisions, and incorporating fetal RhD testing in routine screening is highlighted. The overall tone is optimistic, emphasizing the potential lifesaving impact of rapid genetic diagnosis and personalized care interventions.

In this segment of the video, the host introduces the concept of rapid and Ultra rapid whole genome sequencing for diagnosing genetic conditions quickly. The importance of pharmacogenomic testing in personalized drug treatment based on genetic predispositions is also highlighted. Additionally, the use of non-invasive prenatal testing (NIPT) for fetal antigens is discussed, with a focus on how NIPT technology has evolved to assess the likelihood of inherited genetic conditions. The speaker provides insights into billion to one’s launch of an antigen version of NIPT in late 2022 and explains the significance of antigens during pregnancy.
00:05:00
In this segment of the video, the speaker discusses the importance of testing for RH type early in pregnancy. RH-negative pregnant individuals can develop antibodies that may attack the baby’s blood cells, leading to severe conditions like hemolytic disease of the fetus and newborn (HDFN). To prevent this, RH-negative pregnant individuals can receive Rhogam. The speaker also mentions other fetal antigens that can cause HDFN, emphasizing the importance of screening for these antigens. It is noted that the standard of care regarding Rhogam may change based on future data, and in Europe, cell-free DNA testing is used to determine the necessity of Rhogam due to a shortage of the treatment.
00:10:00
In this part of the video, the speaker discusses the use of cell-free DNA testing in pregnancy, particularly for determining the antigen status of the baby. They explain that if both parents are negative for a specific antigen, the baby will also be negative. The speaker mentions the importance of knowing the paternal status for certain antigens and the use of genotyping for accurate results. The video emphasizes the need for monitoring and potential interventions, such as Rhogam administration, in cases where maternal antibodies are present. Monitoring involves tracking antibody titers and taking appropriate steps based on the results.
00:15:00
In this segment of the video, the speakers discuss the monitoring process for patients with fetal anemia, including routine blood draws, ultrasounds, and possible fetal blood transfusions if needed. Maternal Fetal Medicine specialists are crucial for monitoring and managing these cases. The speakers also touch on the benefits of whole genome sequencing in the NICU and highlight the importance of quick diagnosis for saving infants’ lives. The video also provides information about coffee from Four Sigmatic and True Gene Diagnostics.
00:20:00
In this segment of the video, the speaker discusses the importance of identifying patients at risk for severe fetal anemia through genotyping and Cell free DNA testing. Streamlining management and personalizing care for at-risk patients is highlighted to prevent unnecessary interventions and ensure appropriate monitoring. The speaker emphasizes the use of the Unity blood test to determine fetal status efficiently, especially in cases of antibody screens for various antigens. The technology’s straightforward application, demonstrated through the example of the Kell gene variant and detection in fetal cell free DNA, is explained to ensure accurate identification of fetal status and informed medical decisions. The necessity for high sensitivity in the test results is stressed to ensure precise management based on fetal fraction and variant detection.
00:25:00
In this segment of the video, it is explained how confidence in test results is ensured by checking the signal for antigens in babies and mothers. The chances of missing a condition like Down syndrome in screenings are rare, with a one in ten thousand risk. The validation process for the tests has been 100% accurate so far, using pre-clinical and clinical samples. A registry is in place where newborns are genotyped to confirm results. The importance of genetic counseling and the lack of routine screening for certain conditions like Kell status are highlighted. The speaker discusses the need for proactive testing and the involvement of genetic counselors in patient counseling and decision-making.
00:30:00
In this segment of the video, the speaker discusses the importance of avoiding mixing of blood and recommends using confident information for medical management decisions. They mention that genetic counselors can play a role in advocating for a new testing option called Unity, which includes various tests like carrier screening and fetal RhD testing. The minimum gestational week for ordering this test is 10 weeks. The speaker explains the benefits of integrating the Unity test into routine testing for accessibility, affordability, and quick reporting. The inclusion of fetal RhD testing within the Unity test helps to identify issues like alloimmunization efficiently without the need for additional blood draws.
00:35:00
In this segment of the video, the speaker discusses the process of analyzing data and issuing a new report with additional information related to Down syndrome. The report includes extra details that are only analyzed and reported if ordered. The turnaround time for the report is around five to seven days, allowing for quick incorporation into counseling and medical management for families. The conversation ends on a positive note, praising the speaker’s articulate communication style and expressing enthusiasm for the informative discussion.
