Shocking Truth About Diagnosing Long COVID
A recent study published in Annals of Internal Medicine reveals that current lab tests are ineffective for diagnosing Long COVID. Researchers found that none of the 25 standard blood and urine tests they examined could accurately identify the condition. This underscores a crucial point highlighted by Dr. Kristine Erlandson, the study’s lead researcher from the University of Colorado Anschutz Medical Campus. She emphasized that doctors should focus more on assessing patient symptoms rather than relying on lab results for diagnosis.
Long COVID, which affects approximately 7% of adults in the U.S., or nearly 18 million people, often develops weeks after a COVID-19 infection and involves persistent symptoms that can last for months or even years. Despite its growing prevalence, the study found that standard lab tests are not helpful in diagnosing this complex condition.
The research was part of the National Institutes of Health (NIH) RECOVER initiative, which aims to better understand Long COVID. Data from over 10,000 participants were analyzed, with about 86% having a history of COVID-19. Previous studies within RECOVER had identified a set of 12 symptoms linked to Long COVID, but the latest study focused on whether lab tests could provide a reliable diagnostic tool.
Dr. David Goff from the National Heart, Lung, and Blood Institute (NHLBI) stressed the importance of discovering reliable biomarkers to improve diagnostic accuracy and patient care. However, the study found that traditional blood and urine tests did not aid in distinguishing Long COVID cases from others.
Looking ahead, researchers will explore whether blood and spinal fluid samples from RECOVER participants might lead to new diagnostic methods. Until then, the best approach remains thorough patient history and clinical assessment, with a focus on the 12 identified symptoms to diagnose and manage Long COVID effectively.
