Focused tests for symptoms, possible deficiency or endocrine questions.
The clinical question
Chemistry equipment does not automatically supply every immunoassay or specialty method.
What to discuss next
Ask about the specific indication, intended scope, responsible clinician or laboratory, and the availability of the pathway. The team must confirm arrangements before care or testing can be planned.
These linked method descriptions explain their specimen, analytical scope and limits. The status of a method and the availability of a service are separate considerations.
thyroid-context / Endocrine
Selected thyroid measurements
Planned
A question-led thyroid assessment with the exact tests defined by the clinician.
Question
Which thyroid measurements fit the symptoms, history and medication context?
Specimen
Serum or assay-validated plasma
Preparation
Report medicines and supplements to the clinician; any required change or collection timing must come from the clinical team.
A single value is interpreted against the assay, clinical context and relevant interferences. A universal broad hormone bundle is not assumed.
nutritional-measures / Nutrition & metabolism
Selected nutritional measurements
Planned
Focused tests chosen to investigate a defined concern, not an automatic supplement prescription.
Question
Is a particular nutritional measurement useful in this clinical context?
Specimen
Analyte-specific serum, plasma, whole blood or urine
Preparation
Supplement use, recent intake and specimen handling should follow the selected method’s instructions.
Platform
Validated assay-specific chemistry or targeted chromatographic measurement
Analytical scope
Specified nutrient or related marker, to be released
Interpretation limits
Concentration in one specimen does not necessarily describe every tissue or prove that supplementation will help.
steroid-lcms / Endocrine
Targeted steroid & hormone measurements
Planned
A contemplated targeted method pipeline with analyte-specific performance requirements.
Question
Could a specific, well-characterized hormone assay resolve an endocrine question?
Specimen
Serum or another specifically validated matrix
Preparation
Collection time, medications and physiologic context may matter; the released method must state the exact requirements.
Platform
Targeted liquid chromatography–tandem mass spectrometry
Analytical scope
Selected steroids or hormones; final assay list pending
Interpretation limits
Low detection limits are not a universal platform property. LOD, LOQ, bias, precision and interferences must be established for each analyte and matrix.
