Insights

A correction was made to C-reactive protein (CRP) unit conversion for the National Health and Nutrition Examination Survey (NHANES) cohort. This adjustment broadened the observed CRP value range in the general population data.

Area of Science:

  • Biochemistry
  • Epidemiology

Context:

  • The National Health and Nutrition Examination Survey (NHANES) is a key resource for population health data.
  • Accurate laboratory unit conversion is critical for reliable epidemiological studies.

Purpose:

  • To correct a unit conversion error for C-reactive protein (CRP) measurements in the NHANES dataset.
  • To ensure the accuracy of CRP values used in population health research.

Summary:

  • A unit conversion error for C-reactive protein (CRP) from mg/dL to mg/L in the National Health and Nutrition Examination Survey (NHANES) data was identified and corrected.
  • The corrected CRP values in the NHANES general population cohort now range from 0.10 to 180.0 mg/L, a wider range than previously reported (0.01 to 18.0 mg/dL).

Impact:

  • This correction enhances the precision of CRP data for epidemiological analysis within the NHANES cohort.
  • Ensures more accurate representation of C-reactive protein levels in the general population for future research and public health assessments.

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
