Why
  1. The study's listed conditions name Asthma, a narrower term within Hypersensitivity.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This is a multicenter, prospective, observational study to evaluate the analytical performance of the Abionic IgE Multi-Allergen Test Panel on the abioSCOPE® device in a U.S. point-of-care environment within a clinical laboratory operating under a CLIA certificate for tests of moderate complexity. The study will assess point-of-care ('external') precision, sample type comparison and correlation with a reference method (Phadia Laboratory System, ThermoFisher Scientific).

Sampling method
Non-probability sample

Study population

  • A minimum of 20 subjects with targeted levels of total IgE are needed to participate in the Operator-to-Operator whole blood study.
  • A minimum of 20 subjects with targeted levels of allergen-specific and total IgE are needed to participate in the capillary whole blood between-run imprecision study in the POL environment.
  • A minimum of 40 subjects with targeted levels of Fel d 1-specific IgE and total IgE are needed to participate in the sample type comparison study. These subjects will be recruited, and their samples analyzed at 1 POL.
  • A minimum of 300 subjects (approximately 100 subjects enrolled and evaluated at each of three sites) and with targeted levels of total IgE are needed to participate in the method comparison study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Provision and understanding of signed and dated written by the subject prior to any mandatory study-specific procedures, sample collection, or analysis.
  • Male or female, 18 years of age or older.

Exclusion criteria

Exclusion Criteria:

  • Subject participating in another study that may influence test results.
  • Subject taking any of the following medications: systemic (inhaled or nasal steroids are allowed), anti-cytokines or cytokines, systemic interferon (injection local interferon α for the treatment of HPV is allowed), anti-IgE therapy (approved or ) or treated with systemic chemotherapy.
  • History of cancer, , or immune deficiency disease.
  • Suffering from a hematological pathology (coagulation disorder, severe anemia) that could interfere with the blood draw procedure.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. POC variance components (in a POL environment):

    * External Precision Study ('reproducibility study' 'site-to-site precision study'): Demonstrate that the imprecision of K3-EDTA venous plasma using the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device (all 5 allergens/allergen mixes and total IgE) in the hands of trained Healthcare Professionals in a Physician Office Laboratory (POL) is within the expected range of the imprecision established in the clinical laboratory by Laboratory Scientists. * Operator-to-Operator imprecision on whole blood: Demonstrate that the between-Operator reproducibility of the total IgE of the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device test results is within the expected range of variability. * Between-run reproducibility: Demonstrate that the between-run reproducibility of venous whole blood samples measured with the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device (all 5 allergens/allergen mixes and total IgE) is within the expected range of variability.

    Time frame: Day 1

  2. Sample type comparison:

    Demonstrate that the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device test results obtained from capillary whole blood correlates well with values obtained from K3-EDTA anticoagulated venous plasma and serum samples.

    Time frame: Day 1

  3. Method comparison

    Demonstrate that test results obtained with the total IgE test of the IVD CAPSULE Allergic Asthma panel on the abioSCOPE device correlates with total IgE test results from the reference method (Phadia Laboratory System, ThermoFisher Scientific).

    Time frame: Day 1

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 5, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
