Hematocrit Testing: Purpose, Procedure, Normal Ranges, and Clinical Importance

Hematocrit testing is a commonly performed blood test that plays a crucial role in evaluating overall health and diagnosing various medical conditions. It measures the proportion of red blood cells (RBCs) in the blood and helps clinicians assess a person’s ability to transport oxygen throughout the body. Often included as part of a Complete Blood Count (CBC), hematocrit testing is simple, quick, and highly informative.

What Is Hematocrit?

Hematocrit (Hct) refers to the percentage of blood volume that is made up of red blood cells. Since red blood cells contain hemoglobin—the protein responsible for carrying oxygen—hematocrit levels provide insight into how efficiently oxygen is being delivered to tissues and organs.

For example, a hematocrit value of 42% means that 42% of the blood volume consists of red blood cells, while the remaining 58% includes plasma, white blood cells, and platelets.

Digital Transformation, Data Security, and Interoperability: Strategic Pillars Driving Growth in the Global Healthcare IT Market

The Healthcare IT Market is undergoing a massive and rapid transformation, serving as the technological backbone for modern healthcare delivery, administration, and finance. Market growth is fueled by increasing government mandates for electronic health record (EHR) adoption, the global push for value-based care models, and the exponential generation of patient data. Core segments include EHR/EMR systems, Picture Archiving and Communication Systems (PACS), Revenue Cycle Management (RCM), and Population Health Management (PHM) tools. The imperative for seamless data exchange across disparate systems—interoperability—is arguably the most critical and complex market driver. Furthermore, the COVID-19 pandemic accelerated the adoption of telehealth and remote patient monitoring (RPM) solutions, making them permanent fixtures in the care delivery model. For group discussion, the paramount concern is cybersecurity and data privacy; as patient records become digitized and cloud-based, the vulnerability to…
