Version Log

Our version log is here to keep you informed about what new and improved in the Results Portal. Each update includes important changes like new metric ranges, better functionality, and updates to make your results even more scientifically accurate. 

Email hello@tinyhealth.com to update to the latest system version. If you choose to update, all prior kits linked to your family’s account will be updated, including those for other family members. Flagged metrics, actions, and the microbiome summary score may change after the update. Updates may take up to 1 week, and you will receive an email notification once the it is complete. Note: updates cannot be undone.

v4.0 -New Taxonomic Data, Range Updates, Vaginal Report Update

Date: 2025-04-17

Taxonomy Classification Updates:
Science release v4.0.0 contains improvements to our taxonomic classification of metagenomic reads. These improvements involved curating our taxonomic database to remove two main types of sequences:

1. Publicly-sourced genomes that have since been removed from public databases due to contamination or misclassification
2. Regions of genomes with ambiguous taxonomic classification.

The overall effect of these changes greatly increases the accuracy of our taxonomic classification. In particular, low abundance false positives and false positives from Enterobacteriaceae genomes have been reduced. In addition, contaminated or misclassified genomes from Akkermansia species, B. infantis and C. difficile have been removed resulting in fewer low-abundance false positives in these groups.

Overall summary of major changes:

1. Reduced C. difficile
2. Reduced Akkermansia
3. Reduced Enterobacteriaceae species: Salmonella, Escherichia dysenteriae
4. Reduced Shannon diversity and Species richness
5. Reductions in low abundance Bifidobacterium infantis

New taxonomic data has the version “Taxonomy v2.0.0”.

Vaginal Report Updates
The vaginal microbiome report has been updated with several important changes:

• Diversity metric removed: this metric is no longer included in the report.
• Metric name updates:
  • Potential Bacterial Vaginosis is now Bacterial Vaginosis–Associated Bacteria
  • Potential Yeast Infection is now Candida Yeasts
• Candida update: Candida krusei has been replaced by Candida dubliniensis.
• Bug fix: 28L (Megasphaera) now correctly appears under Bacterial Vaginosis–Associated Bacteria.
• Updated reference ranges for all vaginal taxa.
• New action cards: personalized suggestions based on your results and survey answers.
• New condition section: shows relevant metrics for:
• Bacterial vaginosis
• Aerobic vaginitis
• Yeast infection
• Urinary tract infection
• Lactobacillus breakdown: now includes a list of common Lactobacillus species found in your sample.
• Aerobic bacteria details: shows which bacteria contribute to total aerobic bacteria.

v3.4.2 -Bug Patch

Date: 2025-03-12

This patch fixes a small bug caused missing PRO data to display as ‘0’.

v3.4.1 -Bug Patch

Date: 2025-02-25
This patch fixes a small bug that was causing a mathematical divide by 0 error.

v3.4.0 -Add Additional Enterobacteriaceae genera to Opportunistic Pathogens

Date: 2025-02-21
This minor release: 

• Expands the Opportunistic Pathogen sub-metrics by adding 4 new genera from Enterobacteriaceae for all age groups and reports:
  • Citrobacter
  • Enterobacter
  • Morganella
  • Raoultella
• It also changes the lower detection limit of Total aerobic bacteria in vaginal samples.
• Fixes a bug where strains were not displayed for HMO-digesting species

v3.3.0 - qPCR Results in App and pdf

Date: 2025-02-07
This minor release adds qPCR results from the add-on qPCR Detection test for Candida and H. pylori to the app and the report pdf. Kits that had qPCR results previously emailed can now be found in app.

v3.2.0 - New Metric Release & Bug Fix

Date: 2025-01-24
This minor release introduces two new metrics and a bug fix:

• New metrics: Unconjugated bile acids and Secondary bile acids. These can be found under Microbial Enzymes & Metabolites > Modified Bile Acid Production Capacity.
• Bug fix: This patch fixes a bug where some action cards triggered for Hexa-LPS were appearing for the wrong age group. Cards are now properly displayed.

v3.1.1 - Ammonia Bug Fix

Date: 2024-12-03
This patch fixes a bug where the defined ranges for Ammonia were incorrect. The ranges have now been updated for all age groups to ensure accuracy.

v3.1.1 - New Metric Release

Date: 2024-11-14
This minor release introduces two new metrics:

• Methane producing capacity, located alongside Methanobrevibacter smithii under Disruptive Microbes > Methane Production.
• Species Richness: Added alongside the Shannon Diversity index under Balance and Robustness > Microbiome Diversity > Species Richness. This metric provides an expanded view of the diversity within the microbiome ecosystem.

v3.0.0 - Major Version Update

This is a major version update. 

All metric evaluations in the baby, toddler, child, and adult reports have been updated. Metric evaluations were calculated based on normalized distributions of thousands of microbiomes across all age ranges. Evaluations in reports under v3 are not comparable with v2 report evaluation. Microbiome summary scores (MSS) have also been updated to reflect metric evaluation changes.

• Relative abundance: Lower detection limit reduced from 0.05% to 0.005%.
• Opportunistic Pathogens: Due to the updated abundance threshold, evaluations for opportunistic pathogens and other taxa may differ from previous reports.

Science versioning is live. Each report is associated with a science version on release. Major version changes are not automatic, but can be opted for when activating a new kit. 

v2.1.2 - Fix Duplicate Action Card In Toddlers

This patch fixes a bug where duplicate Bifidobacterium probiotic cards were appearing in toddler reports. Cards are now properly filtered for toddlers older than 2 years of age.

v2.1.1 - Functional Metrics Bug Fix

This minor release includes the release of new functional metrics including IPA, BCAA, Ammonia, and GABA production and degradation for toddler, child, and adult reports. This release also fixes a bug that blocked strain tracking from being visible on pregnancy kits.

v2.1.0 - Released Functional Metrics (IPA, BCAA, TMA, Ammonia, GABA)

This minor release includes the release of new functional metrics including IPA, BCAA, Ammonia, and GABA production and degradation for toddler, child, and adult reports. This release also fixes a bug that blocked strain tracking from being visible on pregnancy kits.

v2.0.2 - Bug Fix Patch

This patch fixes a bug where constipation action cards were not showing up for baby or toddler kits for users who filled out their new profile surveys.

v2.0.1 - First Science Version

This includes all major, minor, and patch updates to our science metrics up to Sept 25, 2024. This version is our first recorded version when we started versioning science metrics.
