Predictive Value of the Peripheral Blood Parameters for Preeclampsia
Clinical Laboratory
|March 7, 2022
Summary
White blood cell (WBC) and neutrophil counts are valuable predictors for preeclampsia (PE). Elevated levels of these parameters indicate increased risk and can aid in early detection of PE.
Area of Science:
- Obstetrics and Gynecology
- Hematology
- Pathophysiology
Background:
- Systemic inflammation is a key factor in preeclampsia (PE) development.
- Peripheral blood parameters may offer predictive value for PE.
Purpose of the Study:
- To evaluate the predictive significance of various peripheral blood parameters for preeclampsia (PE).
- To identify independent risk factors for PE development.
Main Methods:
- Retrospective study involving 170 PE patients, 123 healthy pregnant controls, and 122 non-pregnant controls.
- Peripheral complete blood cell counts analyzed using an automatic blood cell analyzer.
- Receiver operating characteristic (ROC) curve analysis to determine predictive significance and cutoff values.
Main Results:
- White blood cell (WBC) count and neutrophil count/percentage were significantly elevated in PE patients compared to controls.
- Lymphocyte and monocyte percentages were decreased in PE patients.
- WBC and neutrophil counts demonstrated higher predictive value (AUC) and were identified as independent risk factors for PE.
Conclusions:
- Peripheral blood parameters, specifically WBC and neutrophil counts, show high sensitivity and specificity for predicting PE.
- WBC and neutrophil counts are confirmed as independent risk factors for preeclampsia development.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

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...

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
