Vitamin Tests in China Check-up Lists and the Specimen Details That Matter
By MyChinaCheckup coordination team · Published
A package row containing “vitamin” is not enough to identify a nutritional blood test. The actual lists reviewed here include individual B12 and folate names, 25-hydroxyvitamin D, an unnamed nine-component serum panel, and vitamin C entries inside urinalysis. Matching these by the word “vitamin” would lose important differences.
Use this guide to establish what a list expressly names, what specimen information is available, and which details need a provider reply. It does not recommend nutrient screening or supplements.
Start with the named measurement
Folate is vitamin B9; vitamin B12 is also called cobalamin. They are different B vitamins even when a combined test name contains both. A vitamin B test may measure one or more vitamins in blood or urine, so the broad family name alone does not specify the complete test. MedlinePlus: vitamin B testing
25-hydroxyvitamin D, also written 25(OH)D, is the form measured by most vitamin D blood tests. Active vitamin D, or 1,25-dihydroxyvitamin D, is a different measurement. A shortened catalogue label such as “Vitamin D” therefore needs clarification before matching it to a specific request. MedlinePlus: vitamin D test
The clinical definitions explain vocabulary. They do not supply missing components or specimen details for any commercial package.
A source-backed crosswalk of six naming problems
Scroll horizontally to see all columns.
| Source and exact label | What the source establishes | What remains unresolved |
|---|---|---|
| Huashan Pudong Women 3: “Folate”, “Vitamin B12”, “25-hydroxyvitamin D” | Three separate named rows | Specimen and laboratory reporting details are not fully stated in those rows |
| Renji East Men 3: “Nine-component serum vitamin panel” / 血清维生素9项 | Serum is explicit, and the panel advertises nine components | The nine names are not supplied; do not add B12, folate or vitamin D by assumption |
| Renji East Women 3: “Vitamin D2/D3” / 维生素D2/D3 | D2/D3 wording is explicit | The short label does not fully specify the measured forms and reporting arrangement |
| Guangzhou Medical First Men 3: “25-hydroxyvitamin D, two-component measurement (mass spectrometry)” | The form, stated component count and method label are explicit | The source does not name the two components; do not silently expand them to a guessed pair |
| Ren’ai Men 3: “Vitamin C” / 维生素C | The item sits within the urinalysis section | It is not evidence of a separately listed blood vitamin-C nutritional-status test |
| Clifford Men 3: “Urine vitamin C” / 维生素C | Urine is explicit in the English label and section context | It does not establish a blood vitamin-C measurement |
The Renji Women 3 source has an item-specific age note. That is catalogue wording to clarify with the provider, not guidance from this article and not an eligibility rule for the whole package.
A mixed row needs the same care. Huashan Pudong Women 2 names folate and B12 together with erythropoietin and ferritin. Preserve all four source names, but do not describe the row as four vitamins or expand it into a complete micronutrient screen. The label alone does not explain how its results are grouped.
Why the urine vitamin C example changes the comparison
The short Ren’ai item name could look like a nutritional measurement if copied out of context. Its Men 3 PDF, page 4, places vitamin C after the other urinalysis components and before the next blood-glucose section. The Clifford Men 3 PDF, page 7, names urine vitamin C under urinalysis and urine microscopy.
Those documents support a precise correction: retain the specimen context when making a comparison. They do not establish why a particular laboratory includes the urine component, its analytical method, or how to interpret it. Ask the laboratory for those details if they matter to an existing clinical request.
The nine-component serum panel creates the opposite problem: the specimen is clear, but the analytes are not. Its Renji East PDF, page 4, explicitly asks the reader to confirm the individual tests. Neither the number nine nor the serum label closes that gap.
What appeared across the 78-page corpus
The audit counted package pages, once per naming category, using the complete captured item tables. The categories overlap and must not be added to rank packages.
Scroll horizontally to see all columns.
| Expressly named category | Matching pages |
|---|---|
| 25-hydroxyvitamin D, including the two-component method label | 13 |
| Vitamin B12, including a mixed multi-analyte row | 5 |
| Folate, including that mixed row | 4 |
| Nine-component serum vitamin panel with unnamed components | 1 |
| Vitamin C under Ren’ai urinalysis, with the short item label | 6 |
| Explicitly labelled urine vitamin C at Clifford | 6 |
These counts describe published wording, not who needs a test or how often it should be performed. A missing named row is not proof of exclusion. Unspecified panels remain unresolved, and the corpus is limited to these 78 Shanghai and Guangzhou pages.
Turn an unclear label into an answerable question
For an existing test request, first record the analyte, then the specimen, then any stated method or component list. Keep the original package wording alongside those fields. A “match” should not rely solely on both rows mentioning vitamins.
Scroll horizontally to see all columns.
| If the list says… | Ask this documentation question |
|---|---|
| Vitamin D | What is the exact measured form and report name? |
| Two-component 25-hydroxyvitamin D | Please name both components and state whether each is reported separately or with a total |
| Nine-component serum vitamin panel | Please provide the nine individual test names and any package-specific restrictions |
| Vitamin C inside urinalysis | Please confirm that this is the urine component and identify the exact laboratory order |
| Folate and B12 in a mixed row | Which separate results does this row provide, and what specimens are required? |
A provider can answer the specification question while leaving clinical suitability for the clinician. A longer component list is not evidence that the package is more appropriate for you.

Scope and sources
Checked 13 October 2026: the 78-page catalogue corpus, the linked example pages and the three catalogue PDFs above. The specimen conclusions for the vitamin C examples rely on the actual section context, not a keyword search alone. Catalogue PDFs corroborate the website presentation; they are not independent confirmation of current hospital availability.
Clinical vocabulary sources are the MedlinePlus vitamin B and vitamin D pages linked above, checked on the same date. This is educational test-list guidance. It makes no recommendation about a personal testing bundle, frequency or supplement use.
