Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Serum Laboratory Studies, Stool Test, Breath Test

Serum Laboratory Studies, Stool Test, Breath Test

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

Drug Concentrations: Measurements

Drug Concentrations: Measurements

Drug concentration is the quantity of a drug present in a biological sample. Measuring drug amounts in biological samples allows the clinician to understand how a drug is absorbed, distributed, metabolized, and excreted. Samples can be obtained through invasive or non-invasive methods. Invasive techniques involve surgical or parenteral interventions to gather blood, cerebrospinal fluid, or tissue biopsy. Conversely, non-invasive approaches provide samples like urine, feces, and saliva.

Clinically Relevant Drug Product Specifications: Methods of Establishment

Clinically Relevant Drug Product Specifications: Methods of Establishment

Product specifications define the acceptable quality of a pharmaceutical product by ensuring identity, purity, potency, and strength. These specifications serve as benchmarks during development, manufacturing, and post-approval quality control. Clinically relevant specifications are particularly important because they directly relate to a drug's safety and efficacy in clinical use.Dissolution studies are critical biopharmaceutic tools that link in vitro behavior to in vivo performance. They...

Automated Microbial Diagnostics

Automated Microbial Diagnostics

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...

Area of Science:

Clinical Diagnostics
Laboratory Medicine
Healthcare Services

Background:

Point-of-care testing (POCT) is performed near patients, integrating sample collection, analysis, and results.
POCT has expanded to various settings, including homes, pharmacies, and physician offices.
Despite benefits, POCT can be subjective and may exacerbate traditional testing process issues.

Purpose of the Study:

To evaluate the potential and challenges of point-of-care testing (POCT).
To identify areas for improvement in POCT implementation.
To explore the role of POCT in pharmacy patient care.

Main Methods:

Review of current evidence on POCT performance and limitations.
Analysis of preanalytical, analytical, and postanalytical phases in POCT.
Consideration of economic, clinical, and regulatory factors.

Main Results:

POCT can introduce subjectivity and amplify errors in all testing phases.
Inappropriate test requests, unsuitable samples, and inaccurate results are potential issues.
Pharmacy-based POCT presents opportunities but requires addressing several challenges.

Conclusions:

POCT offers significant potential but requires careful management to mitigate risks.
Economic, clinical, and regulatory hurdles must be overcome for successful POCT implementation.
Clear guidelines are needed for optimal POCT integration into diagnostic pathways and disease management.
