Blood Tests

Introduction

Blood tests are laboratory analyses performed on samples of blood taken from a vein or finger-prick. They provide valuable information about a person's health, disease status, and metabolic functions.

Detection of Harmful Substances

Blood tests can detect the presence of harmful chemicals, toxins, and drugs. By measuring their levels and comparing them to normal ranges, clinicians can assess potential risks to health.

Assessment of Body Physiology

Blood tests evaluate the concentrations and proportions of essential metabolites and components in the blood. Differences from normal values can indicate the presence of various ailments, including electrolyte imbalances, nutrient deficiencies, and hormonal disorders.

Regulatory Functions

Blood plays a crucial role in maintaining body pH and core body temperature. It also serves as a hydraulic fluid, transporting vital substances throughout the body.

Pathogen Detection

Blood tests can detect the presence of pathogens, such as bacteria and viruses, by analyzing their specific markers.

Clinical Applications

Blood tests are used for a wide range of clinical purposes, including:

* Diagnosing and monitoring diseases
* Assessing organ function
* Evaluating drug effectiveness
* Determining physiological and biochemical states, such as mineral content and hydration status

C-Reactive Protein Test

Purpose:

The C-reactive protein (CRP) test measures the level of CRP in the blood. Elevated CRP levels indicate the presence of inflammation, a protective response to injury or infection.

Significance:

* Chronic inflammation can cause tissue damage and contribute to the development of diseases.
* A CRP test can help assess the severity and duration of inflammation.
* High CRP levels may suggest underlying health conditions, such as infection, autoimmune disorders, or cardiovascular disease.
