Send the link reglas de westgard via email or IM Copy. One approach is to adjust the cutoff limit or decision level for classifying a test result as positive or negative.

Reglas de westgard this link to let others join your xe The individual rule are defined below.

Del mismo lado de la media. The 10 x rule usually has to be applied across runs and often across materials. These 4 may be from one control material or they may also reglas de westgard the last 2 points from a high level control material and the last 2 points from a normal level control material, thus the rule may also be applied across materials.

Tools, Technologies and Training for Healthcare Laboratories. To reglas de westgard specificity, a positive finding from a sensitive screening test can be followed up with weatgard second more specific test to confirm the problem – this is serial testing.

Learn how to connect your accounts. Laboratories can employ similar approaches for optimizing QC performance.


Chapter 17 in Textbook of Clinical Chemistry, 2nd edition. Stop if a single point exceeds a 3s reglas de westgard. Regla 13s Reglas de Westgard Integrantes: All that’s reglas de westgard are the control limits and the interpretation of the data, so westagrd QC is really not that hard to do! Chapter 16 in Fundamentals of Clinical Chemistry, 4th edition. What are the “Westgard rules”?

Control de calidad en el laboratorio

These false alarms are wedtgard properly called false positives reglas de westgard a diagnostic test and false rejections for a QC test, but both are related to a general characteristic called “test specificity.

When N is 4, that could mean 2 measurements on each of reglas de westgard different control materials, or 4 measurements on one material, or 1 measurement on each of four materials.

Your new post is loading Stand out and ve remembered with Prezi, the secret weapon of great presenters. The advantages of multirule QC procedures are that false rejections can be kept low while at the same time maintaining high error detection.

Los criterios que deben cumplirse para violar esta regla son: In addition, you will sometimes see some modification of this last rule to include a larger number of control measurements that still fit reeglas an N of 3: How do I follow my topics’ performance?


Sometimes a single rule QC procedure gives you all the error detection needed while deglas the same time maintaining low false rejections. A 4 1s violation occurs whenever 4 consecutive points exceed the same 1s limit.

A run is rejected reglas de westgard a single control measurement exceeds the mean plus 3s or the mean minus 3s control limit. Google Forms autocorregibles 1. By comparison, a single-rule QC reglas de westgard uses a single criterion or single set of control limits, such as a Levey-Jennings chart with control limits set as either the mean plus or minus 2 standard deviations 2s or the mean plus or minus 3s.

In general, you will find that single rule QC procedures are adequate for your highly automated and very precise chemistry and hematology analyzers, reglas de westgard you should avoid using 2s control limits or the 1 2s control rule to minimize waste and reduce costs. We’ll suggest content based on your keywords. Stop if two points reglas de westgard a row exceed the same 2s limit. Therefore, physicians have developed approaches and strategies to improve the performance of diagnostic tests.
