About this study

Official title: Clinical Evaluation of Precision for the Potassium and Ionized Calcium Tests Using the i-STAT CG8+ Cartridge With the i-STAT 1 Analyzer for Capillary Specimens.

Assess precision of the i-STAT potassium (K) and ionized calcium (iCa) tests using i-STAT CG8+ cartridge on the i-STAT 1 analyzer.

Read the detailed description

The objective of this study is to assess the precision of the i-STAT K and iCa tests using the IUO i-STAT CG8+ cartridge on the i-STAT 1 analyzer using results from two separate capillary specimens from each subject enrolled in the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Precision assessment

    Assess the precision of the i-STAT potassium (K) and ionized calcium (iCa) tests in mmol/L with the investigational use only (IUO) i-STAT CG8+ cartridge on the i-STAT 1 analyzer using results from capillary specimens from each subject enrolled in the study.

    Measured: Thirty (30) minutes from subject enrollment to the end of the blood draw and testing.

Questions about this trial

What is this clinical trial studying?

An observational study of Hematologic Tests, run by Abbott Point of Care at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Precision assessment (time frame: Thirty (30) minutes from subject enrollment to the end of the blood draw and testing.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2026.
