Diagnostic Kit Validation Services
Regulatory Validation of Salivary Aldosterone Kits
Advance your IVD pipeline with rigorous, evidence-based validation of salivary aldosterone assays. We help in-vitro diagnostics companies generate the sensitivity, specificity, and reproducibility data needed to support CE-IVD or FDA clearance for non-invasive salivary biomarker tests—backed by a workflow designed around real-world clinical sample analysis and regulatory documentation. Salivary aldosterone measurement has been validated for clinical applications including the low-dose ACTH test, and our services are structured to help you meet the analytical evidence expectations of regulatory submissions.
Why Salivary Aldosterone Validation Matters
Salivary aldosterone is emerging as a practical, non-invasive biomarker for conditions such as obstructive sleep apnea (OSA), primary aldosteronism, and cardiovascular risk assessment. Unlike serum or urine sampling, saliva collection is stress-free and patient-friendly, making it attractive for diagnostic workflows that require repeated or home-based sampling. However, translating this biomarker into a regulated IVD kit demands more than a working assay—it requires documented evidence that the test performs reliably across the intended population and clinical context.
Regulatory bodies expect manufacturers to demonstrate analytical validity (sensitivity, specificity, precision, and reproducibility) and, where applicable, clinical validity. For salivary matrices, this includes verifying that the collection device, extraction method, and assay protocol do not introduce matrix effects or variability. Our validation services are designed to generate this evidence systematically, so your submission package reflects the rigor regulators expect.
Evidence for Submission
Generate the analytical performance data—sensitivity, specificity, precision, and reproducibility—that CE-IVD and FDA submissions require.
- Analytical sensitivity and specificity studies
- Intra- and inter-assay precision assessment
- Reproducibility across runs, operators, and sites
Saliva-Specific Validation
Saliva presents unique challenges, including collection device compatibility and matrix effects. Our protocols are designed around these variables.

Validation Workflow Overview
Our validation workflow is structured to mirror the evidence requirements of regulatory submissions while remaining adaptable to your kit's specific design and intended use. Each phase is documented to support your submission package, from initial method verification through final reproducibility studies.
The process is designed to be transparent and collaborative. We work with your team to define acceptance criteria upfront, then execute studies that generate the data you need—without guesswork or ambiguity.
| Phase | Key Activities | Deliverables | Regulatory Relevance |
|---|---|---|---|
| Method Verification | Confirm assay performance in saliva matrix; assess collection device compatibility | Verification report with preliminary sensitivity and precision data | Establishes feasibility before full validation |
| Analytical Validation | Sensitivity, specificity, precision, and reproducibility studies | Validation report with statistical analysis | Core evidence for CE-IVD and FDA submissions |

How Engagement Works
We structure each engagement around your kit's specific design, intended use, and regulatory target. The process is collaborative, with clear milestones and deliverables at each stage.
Define Validation Scope
We begin by reviewing your kit design, intended use, and regulatory target (CE-IVD or FDA). Together, we define the validation parameters, acceptance criteria, and study design—ensuring alignment with regulatory expectations from the start.
Execute Analytical Studies
Our team performs the analytical validation studies, including sensitivity, specificity, precision, and reproducibility assessments. We use saliva-specific protocols that account for collection device and matrix effects, generating data you can rely on.
Analyze Clinical Samples
We run clinical sample panels to assess assay performance in the intended use population. This step provides the clinical context regulators expect, whether for screening, diagnosis, or risk stratification applications.

Analytical Performance Parameters
Regulatory submissions require documented evidence of analytical performance. We design studies to assess the key parameters regulators expect, using protocols that reflect the specific challenges of salivary aldosterone measurement.
Published evidence on salivary aldosterone assays provides a benchmark for expected performance. For example, method validation studies have reported sensitivity in the low ng/L range and intra-assay precision below 10%, with inter-assay precision varying by method and matrix. We use such benchmarks to inform study design and acceptance criteria.
| Parameter | Study Design | Typical Evidence | Regulatory Use |
|---|---|---|---|
| Sensitivity | Limit of detection and quantification studies | Low ng/L sensitivity reported in published methods | Establishes assay's ability to detect clinically relevant levels |
| Specificity | Cross-reactivity and interference studies | Documented cross-reactivity profile | Confirms assay measures aldosterone, not structurally similar steroids |
| Precision | Intra- and inter-assay precision studies | Intra-assay CVs below 10% in published methods | Demonstrates reproducibility within and between runs |
| Reproducibility | Multi-operator, multi-site studies | Consistent performance across conditions | Supports claims of reliable performance in routine use |
