LABS+VALUES STUDY Guide

This set of flashcards covers critical lab values, units, and clinical implications from the ATI-Style Common Lab Tests Study Guide transcript.

CBC

Complete Blood Count

RBC Reference Range

$$4.7-6.1\text{ million/mm}^3$$

RBC Primary Function

Carries oxygen throughout the body

Low RBC Count

Indicates anemia or bleeding

WBC Reference Range

$$5,000-10,000/\text{mm}^3$$

WBC Primary Function

Fights infection within the body

High WBC Count

Indicates infection or inflammation

Hemoglobin (Hgb) Reference Range

$$12-16\text{ g/dL}$$

Hemoglobin Primary Function

Oxygen transport

Hematocrit (Hct) Reference Range

$$37-47\%$$

Hematocrit Definition

The percentage of RBC volume in the blood

Platelets Reference Range

$$150,000-400,000/\text{mm}^3$$

Platelets Primary Function

Clotting

Low Hgb and Hct Significance

Usually points to the presence of anemia

BMP

Basic Metabolic Panel

BMP Primary Focus Area: Glucose

One of the core components measured in a Basic Metabolic Panel to assess blood sugar

BMP Primary Focus Area: Electrolytes

Essential minerals measured to ensure proper bodily function

BMP Primary Focus Area: Kidney Function

Assessed using biomarkers like Creatinine and BUN

BMP Primary Focus Area: Acid-Base Balance

Measurement used to evaluate the metabolic pH status of a patient

BMP Common Usage: Dehydration

A condition frequently assessed using Basic Metabolic Panel values

BMP Common Usage: Kidney Disease

Organ dysfunction commonly monitored via Basic Metabolic Panel tests

BMP Common Usage: Electrolyte Disorders

Imbalances identified during metabolic screening
