Completed

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

Comparison and precision studies will be conducted in up to 5 clinical sites in Israel and the US, and include:

  • Precision
  • Sample Matrix Comparison
  • Method comparison study and flagging analysis
  • Reference interval range

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

3 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adult and pediatric patients with normal (healthy) or abnormal blood counts (known clinical condition)

Description

Inclusion Criteria:

For Residual Samples:

  • Specimen obtained by venipuncture or finger prick and collected into tubes normally used by the site
  • Patient is at least 3 months of age
  • Samples within 8 hours from phlebotomy

For Prospectively collected samples:

  • Subject is at least 22 years of age
  • Non-diseased individuals or, for specific studies, individuals with blood count ranges to cover indicated medical decision points and ranges
  • Samples within 8 hours from phlebotomy

Exclusion Criteria:

Exclusion criteria post blood draw and pre sample scan - For whole blood samples:

  • Visibly hemolyzed or clotted specimens
  • Specimens with insufficient blood volume to complete the procedure
  • Samples older than eight hours

Exclusion criteria post sample scan:

  • Instrument failure or sample rejected by the instrument due to system error or sample mishandling
  • The daily quality control sample measurements indicate that the assay run is outside the specifications for the instrument
  • Operator related error documented in the study records
  • Failure to adhere to study specifics or protocols

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.
Hematology Analyzer - OLO
The investigational device is a quantitative multi-parameter automated hematology analyzer intended for in vitro diagnostic use in screening capillary or venous whole blood samples.
Device: Hematology Analyzer - OLO
Complete blood counts from OLO will be determined from analysis of whole blood samples
Hematology Analyzer - Predicate
The predicate device is a quantitative multi-parameter automated hematology analyzer intended for in vitro diagnostic use in screening patient populations found in clinical and reference laboratories.
Device: Hematology Analyzer - Predicate
Complete blood counts from Predicate will be determined from analysis of whole blood samples

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Reproducibility of CBC parameters provided by the OLO device
Time Frame: 3 months
Reproducibility studies will be conducted using 3 levels of commercial control materials (low, normal and high) to measure all CBC reported parameters. Control material will be run on two instruments at each site. Standard deviation (SD) and coefficient of variation (CV) will be calculated for each measurand for: (1) Between lots/sites; (2) Between instruments; (3) Between days; (4)Between operators/runs; (5) within-run and (6) total variability
3 months
Repeatability of CBC parameters provided by the OLO device
Time Frame: 3 months
Performance of the OLO device will be measured through repeatability of 20 replicates for 11 residual samples on each site. Samples collected for this study will include 4 within lab reference range, 3 around lower medical decision levels for HGB, PLT and WBC, and 4 around the upper range for RBC, HGB, WBC and PLT to cover all pathological levels and medical decision points. Standard deviation (SD) and coefficient of variation (CV) will be computed for each measurand per sample by site.
3 months
Sample Matrix Comparison
Time Frame: 3 months
Paird capillary and venous whole blood samples will be collected. The samples will be analyzed in duplicate on the Sight OLO device. Analysis will include Passing-Bablok Regression analysis per parameter (Bland Altman plots, slope, intercept, with 95% confidence intervals, correlation coefficient, and % bias), between: The average of venous whole blood samples scans and average of capillary whole blood sample scans from the same individual on the Sight OLO device
3 months
Method Comparison
Time Frame: 3 months
Evaluate the performance of the OLO device in comparison to values achieved with the predicate. Analysis will include Regression parameters (slope, intercept with 95% CI) between measurement of Sight OLO and measurement on predicate (Correlation coefficient, Bland Altman plots and overall % bias between predicate and Sight OLO device including % bias at medical decision points).
3 months
Reference Interval Range
Time Frame: 3 months
Establish adult venous and fingerprick reference intervals for the OLO device. The non-parametric method will be used to calculate the lower and upper limits of the reference range.
