Frequently Asked Questions
Common questions about SehatSphere’s free health tools.
Is there a free tool to check vitamin or nutrient deficiency online?
Yes. The Nutrient Deficiency Symptom Finder is completely free and matches your symptoms against 6 common deficiencies — iron, B12, vitamin D, zinc, magnesium and protein — in under 2 minutes, with no signup required.
How can I check my blood test report online for free?
Use the Blood Report Decoder. Enter your values from a CBC, vitamin panel, thyroid, sugar, lipid or kidney test, and it instantly highlights which values are within range and which patterns may need attention.
What is a biological age calculator and how accurate is it?
A biological age calculator, like our Biological Longevity Audit, estimates how your daily habits (sleep, activity, stress, metabolism) compare to your actual calendar age. The science comes from epigenetic clock research at the National Institute on Aging. Our version is a self-awareness estimate, not a medical-grade diagnostic test.
Do I have to pay or sign up to use these tools?
No. All three tools are free to use. You can start any of them immediately — some may ask for basic details only if you want your personalised report saved or shared.
Can these tools replace a doctor’s diagnosis?
No. These tools are designed for general education and self-awareness only. They can help you notice patterns worth discussing, but they don’t replace a proper clinical evaluation, lab test, or a qualified doctor’s advice.
Which tool should I use first?
If you have specific symptoms (like fatigue or hair fall), start with the Symptom Finder. If you already have lab results, use the Blood Report Decoder. If you want a broader lifestyle check-in, try the Biological Longevity Audit.
