Proficiency program

We are happy to offer your Organization the ability of using the BCW Serology Panel to broaden quality control and training programs, and be part of an international database where Participant Organizations measure their performance statistically.

This independent, private Serology Proficiency Panel includes a combination of any or all of the following markers:

  • Chagas
  • HIV - Human Immunodeficiency Virus
  • HBsAg - Hepatitis B Surface Antigen
  • HCV - Hepatitis C
  • HTLV - Human T Lymphotropic Virus
  • HBc - Hepatitis B Core
  • RPR - Syphilis
Five possible configurations
Online results reporting
Instant individual on-line scoring
Participants will be looking for qualitative results: Positive/Reactive or Negative/Non-Reactive
Statistically measured performance presented graphically

Each BCW Serology Panel contains ten vials, regardless of marker configuration. Each vial contains at least 1.5mL of frozen plasma. The BCW Serology Panel can be configured in one of the following five options:


Each BCW Serology Panel will be assigned a unique Panel ID that will be used for online results reporting and comparison with other panels that have the same configuration. Similarly, each vial has a unique ID that will be used for marker results reporting and comparison with all other vials that have been tested for the same marker, regardless if they make up or not panels with the same configuration.

Scoring & Comparison Features

Depending on the BCW Serology Panel configuration chosen, the Participant will have to test each vial for the number of markers that make up the panel. For example: if Panel 7 is ran, then each vial will have to be tested for positive or negative results for the seven markers that make up that panel; in total the ten vials in a Panel 7 will report 70 results, positive or negative (ten vials each tested for seven markers). Since individual vial results will be positive or negative for each marker tested, there will be possibility to report a false positive or false negative for any number of markers on any vial.
Vials then will be scored individually and also in an aggregated basis considering the applicable markers; when we say scoring we refer to how your positive and negative results match registered results, and how many false positives and false negatives are reported. Scoring will be processed immediately after the Participant Organization has entered its results online and the following seven indicators will be provided for each vial and the aggregate full panel, in chart and graph formats.
Rate of Correctly Classified (RCC) Number of true positives plus number of true negatives divided by the total number of samples.
Rate of False Positives (RFP) Number of false positives divided by the total number of negatives (1-Specificity).
Rate of False Negatives (RFN) Number of false negatives divided by the total number of positives.
Positive Predictive Value (PPV) Number of true positives divided by the total number of positives.
Negative Predictive Value (NPV) Number of true negatives divided by the total number of negatives.
Rate of True Positives (RTP) Number of true positives divided by the total number of positives registered (Sensitivity).
Rate of True Negatives (RTN) Number of true negatives divided by the total number of negatives registered (Specificity).

Taking two of the above indicators (sensitivity against the measure of 1-specificity) the BCW Serology Panel presents the Receiver Operating Characteristic curve (ROC curve) for each vial, marker and the aggregate panel.

The area under the ROC curve (AUR), minimum of 0.5 and maximum of 1, will be the value calculated immediately for all panels and markers right after the results are reported online. The graphic presentation of the corresponding ROC curves will show area shapes and values that will allow comparisons to be taken on a relative basis; therefore comparisons are valid for panels with the same configuration or different configuration as well as by marker. Additionally, Participants will be asked to categorize their institutions at the moment of ordering their BCW Serology Panels, therefore comparisons will be available for peer groups as follows:

  • Blood Centers
  • Medical Centers
  • Medical Laboratories
  • Plasma Centers
  • Private Research Institutions
  • Government Research Institutions
  • Private Medical Offices

However, you also may choose to instruct us to charge your account at FedEx or DHL; please note that only FedEx or DHL services will be used, depending on the country of destination.
  • The BCW Serology Panel sample contents will be shipped frozen under current international standards for biological specimens for research purposes. Shipments will be made under modality of cost and freight paid but with any applicable duties unpaid, meaning that BioCollections Worldwide, Inc. will be responsible for packaging, documenting and delivering your order at your country's Customs point of entry.
  • Please be prepared to anticipate that sanitary-health controls may apply at your country's Customs point of entry.
