Clinical Validity: Saliva vs. Serum

For the practicing physician, the primary advantage of SpitCheck® lies in its ability to measure non-protein-bound hormones. While serum tests measure total hormone levels (including those bound to SHBG or Albumin), saliva captures the fraction that has diffused into the extravascular space—representing the biologically active component.

Key Comparative Advantages:

  • Diurnal Mapping: Effortless collection of multiple data points (e.g., 4-point cortisol) without repeated clinic visits.
  • DNA Integrity: Our stabilization buffer maintains high-molecular-weight DNA for long-read sequencing and NGS applications.
  • Reduced Stress Artifacts: Needle-free collection eliminates "white coat" cortisol spikes, ensuring baseline accuracy.

Diagnostic Applications

Endocrinology

Monitor bioavailable Estradiol, Progesterone, and Testosterone for HRT optimization.

Cardiometabolic

Detect early-stage insulin resistance through salivary insulin and glucose-6-phosphate.

Oncology

Non-invasive screening for high-risk genetic variants (BRCA1/2, Lynch Syndrome) via high-yield DNA extraction.
