Summary
External quality assessment (EQA) is crucial for diagnostic testing quality, especially in hemostasis. This review examines EQA
Area of Science:
- Laboratory medicine
- Diagnostic testing quality
Background:
- Quality assurance in diagnostic testing is essential.
- Laboratories use internal quality control and external quality assessment (EQA) to ensure testing quality.
- EQA is particularly important for hemostasis and coagulation tests.
Purpose of the Study:
- To review the strengths and weaknesses of external quality assessment (EQA) in laboratory medicine.
- To identify opportunities for harmonizing EQA practices.
- To improve outcomes for participating laboratories, patients, and healthcare providers.
Main Methods:
- Review of existing literature and practices in external quality assessment (EQA).
- Analysis of EQA provider support mechanisms, including proficiency testing and educational resources.
- Examination of EQA's role in laboratory accreditation.
Main Results:
- EQA provides critical data on test accuracy and long-term laboratory performance.
- EQA providers offer valuable support through proficiency testing, expert advice, and educational materials.
- Participation in EQA is frequently a requirement for laboratory accreditation.
Conclusions:
- EQA plays a vital role in maintaining and improving diagnostic testing quality.
- Harmonizing EQA practices can enhance its effectiveness and benefits.
- Optimizing EQA contributes to better patient care through reliable laboratory results.

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

01:24Disorders of Hemostasis
2.3K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

01:09Harmonic Mean
3.8K
The arithmetic mean is usually skewed towards the larger values in the data set. Therefore, to avoid this inherent bias towards smaller values, the harmonic mean is used.
Take the example of the speed of a car, which is the measure of the rate of distance traveled. If the vehicle traverses the same distance back-and-forth, its average speed equals the total distance traveled divided by the total time taken. However, if the car moves with varying speeds, then the arithmetic mean is more skewed...

01:05Introduction to Hemostasis
14.6K
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

01:11Work Done on a System by External Force
3.0K
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting particles. The potential energy formulation helps formulate the effect of internal forces. The net work done by an external force can be written in terms of the total change of mechanical energy, which includes both kinetic and potential energies.

01:21Simple Harmonic Motion
15.4K
Simple harmonic motion is the name given to oscillatory motion for a system where the net force can be described by Hooke's law. If the net force can be described by Hooke's law and there is no damping (by friction or other non-conservative forces), then a simple harmonic oscillator will oscillate with equal displacement on either side of the equilibrium position. To derive an equation for period and frequency, the equation of motion is used. The period of a simple harmonic oscillator is given...
