Scope definition
Clarify the product, batch, intended use, destination and decision the result needs to support. This service does not provide medical advice.
TESTING CONSULTATION
Plan the right ginkgo test before sending a sample
Turn a ginkgo leaf or extract question into a defined laboratory brief, with the assay labels, method basis and batch context kept explicit.
Consultation and coordination, with a clear boundary
We help define the scope, align the method and reporting basis, coordinate with the factory and a selected laboratory, and review the resulting documents with you. The selected laboratory performs the testing and issues its result.
The selected laboratory performs the tests. Confirm its scope, suitable methods, turnaround and intended report use before commissioning.
HOW WE HELP
A practical path from question to comparable evidence
The work starts by fixing what is being tested, why it matters and which basis makes the result useful.
Method and basis alignment
Align the method, reference basis, units and requested reporting language before work is commissioned.
Batch and sampling plan
Plan batch identity, representative sampling, retention and handoff. The selected laboratory confirms its own sample requirements.
COA and result review
Compare test-line definitions, methods and units across a COA and laboratory result, explain differences and flag questions for follow-up.
POTENTIAL PROJECTS
Ginkgo leaf and extract consultation scope
These are consultation starting points, not a fixed panel or a promise that every method fits every sample.
总黄酮醇苷 · Total flavonol glycosides
Align the marker-group method and calculation or reporting basis before comparison.
萜类内酯 · Terpene lactones
Define the lactone scope, method and reporting basis appropriate to the material.
银杏酸 · Ginkgolic acids
Clarify screening or quantitation and its reporting basis; no limit is assumed.
Moisture or water
Choose the relevant moisture or water approach for the sample matrix.
Impurities and foreign matter
Define the physical, chemical or process-related impurity question.
Pesticide residues
Align the analyte panel and intended-market basis before quotation.
Heavy metals or elemental scope
Define elements, method and reporting basis without assuming limits.
Microbiological scope
Select the requested count or organism scope and applicable basis.

WORKFLOW
Confirm the basis before commissioning work
- 1
Choose the question
Select the product and the few objectives that matter to the decision.
- 2
Use the free first consultation
We clarify the need and coordinate directly with the factory where useful.
- 3
Confirm method, sample and quote
The selected laboratory confirms method and sample requirements. Testing, samples, shipping, translation and other paid work are quoted for approval.
- 4
Commission and coordinate
Work starts only after scope and charges are confirmed. We coordinate handoffs and help review the documents; the laboratory owns its result.
FAQ
What this service does and does not do
Who actually performs the test?
A laboratory selected and confirmed for the project performs the test and issues the result. We provide consultation and coordination. Any accreditation or method capability must be checked for that specific laboratory and scope.
What is free?
The initial needs consultation and direct factory coordination are free. Laboratory testing, sample purchase or preparation, shipping, translation and any other paid work require a quote and your confirmation before commission.
How much sample is required and how long will it take?
There is no universal amount or turnaround. The selected laboratory confirms sample requirements, method availability and timing after the material and scope are clear.
Does a result guarantee certification or market acceptance?
No. A result applies to the submitted sample, method and reporting basis. It does not by itself guarantee certification, regulatory acceptance, a production batch or any future result.
Can this service replace medical or regulatory advice?
No. It organizes a testing question and supporting coordination. Medical decisions and jurisdiction-specific regulatory conclusions require appropriately qualified professionals.
How are ginkgo assay labels and limits handled?
The simplified Chinese assay labels 总黄酮醇苷, 萜类内酯 and 银杏酸 stay visible to avoid ambiguity. The selected laboratory and client must align the method, calculation or reporting basis and any applicable standard. This page states no numerical pharmacopoeial threshold.
Bring one clear testing question
A useful start is the product, batch context, intended decision and the evidence basis you need. The remaining method, sample and cost details are confirmed before commission.
