Iron markers, ferritin, vitamin B12, vitamin D, zinc and magnesium answer different questions. One result does not always represent nutritional status on its own; method and clinical context matter.
Available lab values (2)
- Potassium (K)Serum or plasma potassium is commonly reported in mmol/L or mEq/L. Reference intervals vary by laboratory, specimen and method, so the range on the original report should be used.mmol/l
- Sodium (Na)Blood sodium is commonly reported in mmol/L or mEq/L and reflects the relationship between sodium and water balance. The laboratory-specific reference interval should be used.mmol/l
A lab category organizes tests — it does not define disease relevance
Grouping markers by organ system or laboratory topic helps navigation. The category itself says nothing about whether a particular illness is relevant to an individual result.

Use the broader biomarker overview to understand where the test sits without adding a disease interpretation.
Open lab markersQuestionnaires
Keep symptom documentation separate
Questionnaires can describe symptoms and function, but they do not turn a laboratory category into a diagnosis.
Open questionnairesKnowledge
Select the clinical topic explicitly
If your question concerns a specific health topic, choose it directly from the knowledge overview.
Open knowledge overviewFurther orientation
Use related information without turning the category into a diagnosis
A category page only organizes laboratory information. Symptoms, function, and illness-specific questions should be documented or explored separately rather than inferred from the category.

Questionnaires
Document symptoms independently
Structured assessments can record symptoms and function without treating a lab result as their cause.
Knowledge
Choose a disease or symptom topic explicitly
Use the knowledge overview when the real question is about fatigue, ME/CFS, PEM, pacing, or another clinical topic.

Frequently asked questions
Which tests are used to assess iron status?
Ferritin, transferrin and transferrin saturation are commonly used, with serum iron added in some settings. Ferritin can also rise with inflammation, so context matters.
Which vitamins and minerals are commonly tested?
Depending on symptoms and risk factors, tests may include vitamin B12, folate, vitamin D, iron markers, magnesium and zinc. Broad testing without a clinical question is not always useful.
