Blood Studies I: ABG and VBG

812
Blood studies are critical in the medical field, enabling healthcare professionals to assess a patient's health status accurately. This page will focus on two significant blood studies: Arterial Blood Gas (ABG) and Venous Blood Gas (VBG).
Arterial Blood Gas (ABG)
Arterial Blood Gas (ABG) studies are crucial for assessing the lungs' ability to supply oxygen and remove carbon dioxide, reflecting the patient's ventilation status. They also help understand the kidneys' capacity to...

Area of Science:

  • Medical Science
  • Parasitology
  • Public Health

Background:

  • Babesia parasites cause transfusion-transmitted babesiosis (TTB), with hundreds of cases reported historically.
  • In May 2020, the American Red Cross (ARC) initiated blood donation screening for Babesia in endemic US regions.

Purpose of the Study:

  • To evaluate the effectiveness of Babesia screening in preventing TTB.
  • To assess the prevalence of Babesia in blood donations.

Main Methods:

  • 1,816,669 donations were tested using a nucleic acid test (NAT) for Babesia 18S rRNA.
  • Reactive donations underwent serological testing for B. microti antibodies.
  • Investigations were conducted for suspected TTB cases.

Main Results:

  • 365 NAT-reactive donations were identified in the first 13 months.
  • B. microti antibodies were present in 79% of reactive donations.
  • No cases of transfusion-transmitted babesiosis were identified during the study period.

Conclusions:

  • Babesia screening of blood donations is an effective strategy for eliminating TTB.
  • The implementation of blood testing has successfully prevented TTB transmission.
