Measuring and analyzing your curation will help you to understand what your audience is looking for and how to improve your performance. In addition, you will sometimes see some modification of this last rule to include a larger number of control measurements that still fit with an N of 3: These false alarms are more properly called false positives for a diagnostic test and false rejections for a QC test, but both are related to a general characteristic called “test specificity.

Often the 4 1s and 10 x must be used across runs in order to get the number of control measurements needed to apply the rules. Computer applications don’t need to use the 1 2s warning rule.

I don’t have a Facebook or a Twitter account. The well-known Westgard multirule QC procedure uses 5 different control rules to judge the acceptability of an analytical run.


Delete comment or cancel. To improve specificity, a positive finding from a sensitive screening test can be followed up with a second more specific test to confirm the problem – this is serial testing. How do you perform multirule QC? Send link to edit together this prezi using Prezi Meeting learn more: Everything you ever wanted to know, or possibly didn’t want to know, about multirule QC.

Autoevaluacion con formularios de Google 1. Regla 13s Reglas de Westgard Integrantes: Not only will it drive traffic and leads through your content, but it will help show your expertise with your followers.

It’s like a yield or warning sign at the intersection of two roads. How to integrate my topics’ content to my website? In addition, you will sometimes see some modifications of this last rule to make it fit more easily with Ns of 4: Laboratories can employ similar approaches for optimizing QC performance.

Tools, Technologies and Training for Healthcare Laboratories. When should you use a multirule QC procedure?

Do you really want to delete this prezi? How can I send a newsletter from my topic? We prefer to use subscripts to indicate the control limits, but other texts and papers may use somewhat westgafd notation e. I will also have to admit that around our house it is Mrs.

“Westgard Rules”

This generally means eliminating the 1 2s rule because of its high false rejections and considering others such as 1 2. Now for a more technical description. Branding your topics will give more credibility to your content, position you as a professional expert and generate conversions and leads.


One approach is to adjust the cutoff limit or decision level for classifying a test result as positive or negative. Yes, a QC test is like a diagnostic test! First, a non-technical description. What are the “Westgard rules”? All that’s changed are the control limits and the interpretation of the data, so multirule QC is really not that hard to do!

It’s like running two liver function tests and diagnosing a problem if either one of them is positive.

Your new post is loading Si hay cuando menos una diferencia de 4s entre los valores de control dentro de una sola corrida, se viola la regla para error aleatorio.

Creating downloadable prezi, be patient. We’ve talked about Westgard Rules for decades, and we’ve talked about Six Sigma for years. Another approach for optimizing diagnostic performance is to use multiple tests. In general, you will find that single rule QC procedures are adequate for your highly automated and very precise chemistry and hematology analyzers, but you should avoid using 2s control limits or the 1 2s control rule to minimize waste and reduce costs.

True alarms or error detection are maximized by selecting a combination of the rules most sensitive to detection of random and systematic errors, then rejecting a run if any one of these rules is violated parallel testing. A 4 1s violation occurs whenever 4 consecutive points exceed the same 1s limit. Why should I share my scoops? The remaining issue is whether adequate error detection can be provided by these other single rule QC procedures.

Houston, we have a problem!
