A recent study revealed that a liquid-biopsy approach that measures DNA-methylation levels in the blood may improve the detection of pregnancies at risk of developing preeclampsia at early stages.

About Preeclampsia: 

  • It is a serious blood pressure condition that develops during pregnancy.
  • It typically develops after the 20th week of pregnancy.
  • It can also affect other organs in the body and be dangerous for both the mother and her developing fetus. 
  • Symptoms:
    • People with preeclampsia often have high blood pressure (hypertension) and high levels of protein in their urine (proteinuria).
    • Changes in vision, including temporary loss of vision, blurred vision or light sensitivity
  • Prevention
    • Medication: The best clinical evidence for prevention of preeclampsia is the use of low-dose aspirin. 
    • Lifestyle and healthy choices: If one had preeclampsia before, it's a good idea to be as healthy as you can be.


What is liquid biopsy?

  • A liquid biopsy is a simple and non-invasive alternative to surgical biopsies which enables doctors to discover a range of information about a tumour through a simple blood sample.


Q1) What is biopsy?

A biopsy is a medical procedure in which a small sample of tissue or cells is taken from the body for examination under a microscope or for other laboratory testing. Biopsies are commonly performed to diagnose or investigate various medical conditions, including cancer, infections, autoimmune diseases, and other disorders.
