Breast Cancer Surgery May Soon Be Completed Successfully without Requiring Clinical Laboratory Testing and Pathology Reports

Proof-of-concept research investigates whether photoacoustic imaging can be used in place of traditional tissue staining procedures during cancer surgery to determine if all of the tumor has been removed Determining where breast cancer ends and healthy tissue begins is a critical part of breast cancer surgery. Surgeons are used to working closely during surgery with anatomic pathologists who generate pathology reports that specify the surgical or tumor margin, an area of healthy tissue...

Top Biologists Call for Moratorium on Use of CRISPR Gene Editing Tool for Clinical Purposes Because of Concerns about Unresolved Ethical Issues

Most pathologists know that CRISPR can permanently repair DNA to eliminate diseases that plague families, but also could be used for less ethical purposes, say experts Gene editing is a rapidly developing field that is expected to create new diagnostic needs that can be filled by pathologists and by new medical laboratory tests. However, experts in bio-ethics are voicing concerns that gene editing for clinical purposes is moving forward without proper consideration of important ethical issues...

Collaboration of Caltech Engineers and LeukoDX Produces Prototype Point-of-Care Device That Counts White Blood Cells in Minutes in the Patient’s Home

The science behind the device is an innovative detection assay of dyes that stain leukocytes so they will fluoresce and enable differentiation of white blood cell subtypes  Over the last couple of years, medical laboratory technology developers have brought a number of FDA-approved point-of-care (POCT) and home self-tests to market. These medical tests run the full spectrum. They include tests to detect HIV, malaria, pregnancy or male fertility, drug use or Hepatitis C. There are tests to...
