  1. To assess the validity and reproducibility of the MP Diagnostics HTLV Blot 2.4.
  2. To conduct a sensitivity analysis of the HTLV Blot 2.4 using a known positive population.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a retrospective study designed to assess the validity and reproducibility of the MP Diagnostics IVD device, the HTLV Blot 2.4 (MP Blot), in various populations. The study will be conducted at three geographical distinct locations.

The validity of the MP Blot will be assessed by calculating the following:

  1. Percent negative agreement with CDPHL Algorithm on 200 EIA negative specimens
  2. Percent positive agreement with CDPHL Algorithm on 200 EIA repeat reactive specimens

The sensitivity of the MP Blot will be evaluated by testing 200 known positive specimens. The study will be performed using three product lots at three clinical sites.

The reproducibility of the MP Blot will be assessed by testing two replicates of a three member panel at three clinical testing sites with each of three lots of product over multiple days by three operators.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EIA Negative
Blood donor specimens that tested non-reactive by previously licensed HTLV screening assay.
Other: CDPHL Algorithm
Supplemental testing algorithm performed by the CDPHL.
EIA Repeat Reactive
Blood donor specimens that tested repeat reactive by previously licensed HTLV screening assay, but are unconfirmed.
Other: CDPHL Algorithm
Supplemental testing algorithm performed by the CDPHL.
Known Positive
Blood donor specimens that tested repeat reactive with a licensed HTLV screening assay and have been confirmed through additional, unlicensed supplemental testing.
Other: CDPHL Algorithm
Supplemental testing algorithm performed by the CDPHL.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
