Celiva

Saliva has a lot to say.

Its microbes, its antibodies, and how they change over time. We’re building the models to listen.

Two readings from the same sample, over time.

Each sample holds the oral microbiome and the body’s antibodies. Both shift with diet, medication, inflammation and immune state. Sampled again and again, we can watch how each changes, and when they change together.

No one is modelling the conversation.

Your immune system and your oral microbiome talk every day, and saliva carries both sides. We read them together, and keep reading.

Collect.

A little saliva, as often as a study needs. No needle, no clinic.

Read.

We read a DNA tag that names each bacterium, to see who is there and in what proportion, and add salivary antibodies from the same sample.

Model.

Our models look for microbes and antibodies that move together within a person, to see whether shifts appear before symptoms.

Every sample makes the next model sharper.

Your mouth is a busy border.

Hundreds of species live in your mouth, and more arrive with every breath and bite. Antibodies in saliva keep that community in balance, and leave a record there.

Saliva analysis for research teams.

Send us saliva. We handle the rest.

Microbiome and salivary antibodies from one tube, sampled as often as your study needs.

Built for

  • Clinical studies

    Repeated, needle-free microbiome and antibody readouts between clinic visits.

  • Research groups

    Paired saliva data over time, without building a sequencing lab.

  • Oral care and probiotics

    See whether a product shifts the oral community, and the antibodies alongside it.
