Practical check-up guide
CRP, hs-CRP and ESR in China Check-up Package Lists
By MyChinaCheckup coordination team · Published
CRP, high-sensitivity CRP and ESR should occupy separate lines when you reconcile a check-up package with an existing test request. They concern inflammation, but the names do not identify one interchangeable examination. A panel heading can also mention CRP without settling how that panel is ordered or reported.
An audit of 78 public MyChinaCheckup package pages in Shanghai and Guangzhou found all three kinds of wording. This guide turns those actual labels into a practical name-matching aid. It does not recommend an inflammation-testing bundle or explain an individual result.
What the three names identify
CRP means C-reactive protein, a protein measured in blood. A CRP result does not by itself identify the location or cause of inflammation. High-sensitivity CRP, commonly written hs-CRP, measures the same protein with sensitivity to very small increases; its clinical use differs from a standard CRP test. Preserve “high-sensitivity” when copying a request or report rather than shortening both names to CRP. MedlinePlus: CRP test
ESR means erythrocyte sedimentation rate. It measures how quickly red blood cells settle in a tube. It is a different measurement from CRP concentration. An ESR result alone cannot diagnose the condition responsible for inflammation. Whether either test is useful for a particular person belongs with the clinician. MedlinePlus: ESR
What the catalogue audit found
The unit below is a package page with an expressly matching label, counted once per category. Categories overlap. These are documentation counts within 78 inspected pages, not estimates of hospital availability or screening recommendations.
Scroll horizontally to see all columns.
| Wording category | Pages with a matching label | How it was counted |
|---|---|---|
| Standalone CRP / C-reactive protein, without a high-sensitivity qualifier | 7 | A named item; CRP inside a panel label was kept separate |
| High-sensitivity C-reactive protein | 13 | The high-sensitivity wording had to be explicit |
| Rheumatology panel naming CRP, RF and ASO | 2 | One panel label per page, not three independently confirmed orders |
| Erythrocyte sedimentation rate at one hour | 4 | The component row, not the repeated ESR section heading |
The audit looked at item labels in the complete captured tables. A page without one of these labels remains “not separately named”; an unspecified laboratory panel cannot be expanded from general medical knowledge. The accompanying source-row inventory preserves every match and its URL so that the counts can be checked.
Four source patterns worth recognising
Scroll horizontally to see all columns.
| Catalogue example | Exact wording or structure | What to record |
|---|---|---|
| Ruijin Jiading Men 2 | CRP | CRP is named; the row does not state high-sensitivity |
| Sun Yat-sen Memorial Men 2 | High-sensitivity C-reactive protein (hs-CRP); Rheumatology panel: CRP, RF, ASO | Keep both source labels; ask how the panel and standalone row are ordered and reported |
| Clifford Men 3 | High-sensitivity C-reactive protein (hs-CRP), with Chinese 超敏C反应蛋白测定 | The high-sensitivity qualifier is explicit in both columns |
| Ren’ai Men 3 | C-reactive protein (CRP); an ESR section heading followed by “Erythrocyte sedimentation rate at one hour” | CRP and ESR are separately named; the ESR heading and its component are not two ESR tests |
The Sun Yat-sen Memorial page prints named components in the panel title while its generic detail text says sub-indicators are not fully specified. Preserve that qualification. The presence of CRP in the title supports recording a named component, but does not settle the full panel specification, assay identity or whether any entries duplicate one another operationally.
The Ren’ai Men 3 PDF, page 6, also shows the ESR heading and one-hour component. The Clifford Men 3 PDF preserves the high-sensitivity wording. These are linked catalogue documents, not independent laboratory-order confirmation.
Match the request before comparing packages
Start with the exact test name on an existing clinician request. Then copy the complete package row, including qualifiers and any Chinese wording. Do not replace the source name with a shorter label simply to make two columns line up.
- If the request says hs-CRP and the package says only CRP, leave assay identity unresolved. Ask whether the named order is high-sensitivity.
- If the request says ESR, a CRP row does not close that request. Look for an explicit ESR item or ask for the panel specification.
- If CRP appears inside a named panel, retain the panel name and ask which results are individually reported.
- If an ESR heading is followed by its one-hour component, record the component as the examination and the heading as context.
- If no matching item is visible, write “not separately named in this list”. Do not turn that observation into “excluded” without a provider statement.
These steps resolve documentation, not clinical equivalence. Even after the names match, the clinician must decide whether the proposed examination addresses the intended question.
A blank record for one unresolved line
Use one copy for each test already under discussion. It needs no results or personal identifiers.

| Field | Your record |
|---|---|
| Exact name on request | |
| Package URL and date checked | |
| Exact English and Chinese row, including qualifiers | |
| Section heading or panel name | |
| Status: expressly named / panel detail unresolved / not separately named | |
| Question about assay identity or separate reporting | |
| Provider reply, date and written confirmation reference |
A focused question is: “My existing request says hs-CRP. This package says CRP. Please confirm the exact assay name and how it appears on the report, including whether it is a separate result or part of a panel.” Use it only where it reflects your actual request; it is not a suggestion to order another test.
Scope and sources
Catalogue and linked-document checks: 13 October 2026. The 78-page audit covers the supplied Shanghai and Guangzhou catalogue corpus; it does not represent every China check-up package. Public listings can change. Their wording is a planning reference, not a confirmed booking or a promise that a particular laboratory method is available.
Clinical definitions were checked against the two MedlinePlus pages linked above on the same date. No result thresholds, diagnosis, testing frequency or treatment advice are supplied here. A qualified healthcare professional should interpret results.
