My name is Zsolt. I build clinical tools for labs and longevity clinics, and I release some of them as free public tools.

The Male Hormone Lab Interpreter unique feature is that it visualizes the testosterone production and feedback pathway on HPG axis to identify the true root cause of hormonal imbalances. All hormones are interpreted based on optimal ranges. This is something LLMs still struggles with.

The only difference between public and clinical ones is that the clinical suggest diagnosis and treatment options. But if there is any type of disfunction its obvious from the diagram and differentiating is also straigh forward.

All the tools on the longevity-tools.com are 100% free and private. No email or any data collection, no third party scripts, no tracking scripts. Full privacy.

Check out my other tools:

## Thyroid Function Interpreter https://longevity-tools.com/thyroid-function-interpreter

Visualizes hormones, calculated sensitivities, and secretory capacities on the HPT axis so thyroid dysfunction patterns are easier to recognize.

## Glucose Metabolism Interpreter https://longevity-tools.com/glucose-metabolism-interpreter

Verifies fasting and insulin status, then classifies glucose-metabolism dysfunction using insulin-dependent and non-insulin-dependent markers.

## Liver Function Blood Test Interpreter https://longevity-tools.com/liver-function-interpreter

Calculates liver health scores, runs differential diagnostic logic, helps identify the tissue of origin of elevated enzymes, and surfaces relevant next steps from clinical guidelines.

## Iron Status Interpreter https://longevity-tools.com/iron-status-interpreter

Adjusts ferritin for inflammation, estimates real iron stores, interprets them against optimal targets, and provides guideline-based next steps plus a personalized supplementation plan.

## Grip Strength Interpreter https://longevity-tools.com/grip-strength-interpreter

Shows grip-strength percentiles, estimates all-cause-mortality risk impact, proposes achievable targets, and projects future muscle-weakness risk.

## Humanity's Bortz Blood Age Calculator https://longevity-tools.com/humanitys-bortz-blood-age

The most advanced biological age calculator model based on blood tests available in commercial labs. It was trained on 306k UK Biobank participants and has higher predictive value than Levine PhenoAge.

## Levine PhenoAge Biological Age Calculator https://longevity-tools.com/levine-pheno-age

A biological age calculator based on routine blood biomarkers, developed by Morgan Levine, Steve Horvath, and collaborators. It prioritizes accessibility and low-cost lab markers over maximum precision.
