Questions many people start with.
Which lab values are truly relevant for chronic fatigue?
Ferritin, vitamin B12, TSH and other markers may be part of a medical work-up depending on the clinical question. No single result explains chronic fatigue.
Open fatigue lab valuesWhat does a single value without context really tell me?
A single result should be read with the reason for testing, unit, laboratory reference range, trends and other findings.
Read contextHow do I read a reference range?
Learn what the unit, lab-specific reference range and common influencing factors can mean — without automatically evaluating your individual result.
Browse biomarkersWhere can I find other health topics?
The knowledge overview keeps fatigue, ME/CFS, PEM, pacing, and questionnaires as separate topics instead of inferring them from a lab value.
Open knowledge overview
Your results.
Together over time.
Elara places manually entered lab values alongside symptoms, energy and other longitudinal entries so you can review changes over time and structure them for conversations — without automated medical interpretation.
Manual lab-value entry
Enter values from your lab report manually, together with the unit and reference range shown by the lab.
Trends across multiple measurements
Record values over time and compare them with earlier entries. A trend alone does not determine whether a change is medically meaningful.
Lab values alongside symptom trends
View lab values, symptoms and energy entries over the same time period. Timing can suggest questions to explore, but it is not an automatically calculated correlation or proof of causation.
Good to know
Lab values need to be interpreted in clinical context by qualified healthcare professionals.
Why can lab results be normal in ME/CFS?
There is currently no confirmatory laboratory test and no biomarker with sufficient sensitivity and specificity to diagnose ME/CFS. Routine laboratory results can be normal despite substantial impairment. Testing is therefore mainly used to identify other treatable causes or comorbidities, with additional tests guided by history, symptoms and clinical findings.
How do reference range and optimal range differ?
Reference intervals are established for a particular method and population and can vary between laboratories. Not every threshold is a statistical “normal range”: some tests use clinical decision limits or treatment targets. A universal “optimal range” therefore cannot be derived from a website. The laboratory report, the reason for testing and, when needed, clinical assessment are what matter.
How can Elara help me with my lab values?
Elara lets you manually record lab values alongside symptoms, energy and other longitudinal entries and compare the same time periods. This can help structure changes for a clinical conversation. Elara does not turn these entries into a medical diagnosis, causal inference or validated clinical correlation.
Which values are particularly relevant in Long Covid?
No single laboratory test can definitively diagnose or rule out Long COVID. Appropriate testing depends on the person’s symptoms, medical history and the clinical question being investigated. Laboratory or imaging findings should not be used as the sole measure of a person’s condition or diagnosis.
