Pepsinogen I and II in China Packages: Separate Them from H. pylori Tests
By MyChinaCheckup coordination team · Published
Pepsinogen appears in three formats across the 17 package pages checked here: I and II together in one row, I and II on separate rows, or PGⅠ and PGⅡ inside a named gastric-function panel. Every one of those pages separately names a carbon-13 urea breath test. None explicitly names a pepsinogen I/II ratio or an upper endoscopy in its complete item table.
That pattern matters when an enquiry says only “stomach tests”. It can hide which laboratory measurements, infection-related test and procedure have actually been named. This guide keeps those fields separate and shows exactly where the published wording stops. It audits the MyChinaCheckup operator catalogue on 13 October 2026; it does not independently verify hospital availability, a final laboratory order or individual suitability.
What pepsinogen names describe
The National Cancer Institute describes pepsinogen as a substance produced by stomach cells that is changed into pepsin by stomach acid; pepsin helps digest protein. Its screening review uses PGI and PGII for pepsinogen I and II, and discusses their ratio separately. Those are useful vocabulary distinctions when reading a package list. NCI: pepsinogen and NCI: stomach-screening evidence.
H. pylori is a bacterium. The common infection tests described by MedlinePlus use breath or stool samples; other approaches can use stomach tissue. The fact that pepsinogen and H. pylori both appear in a gastric-health discussion does not make their names interchangeable in an order. MedlinePlus: H. pylori tests.
Upper GI endoscopy is a procedure using a flexible camera to view the upper digestive tract's lining. It is another scope category, separate from a pepsinogen row or breath-test row. NIDDK: upper GI endoscopy.
A cross-provider comparison of 17 pages
Pages with identical wording in these columns are grouped below, and every inspected page is linked. “Not separately named” describes the complete published item table. It does not confirm exclusion from a later hospital plan or establish that an examination is unavailable.

The two Huashan Pudong men's pages contain a combined “Pepsinogen I and II” entry. Their Women’s 03 page splits the names into two rows and adds a separate “Gastrin-17” row. The difference is a change in how names are presented; it does not establish a difference in clinical quality, how many samples are collected or the reporting format.
All six Renji East pages spell out “Pepsinogen I” and “Pepsinogen II” with the Chinese source names “胃蛋白酶原I测定” and “胃蛋白酶原II测定”. They separately print “Gastrin” / “胃泌素”. Keep that wording rather than silently changing it to gastrin-17. The more specific Huashan label does not expand the less specific Renji label.
Clifford's two Select 03 pages place the numbered pepsinogen entries beneath “Gastric laboratory tests 胃功能3项”. The three numbered measurements in that section are gastrin and the two pepsinogens. The carbon-13 breath test has a separate heading and numbered item. The section heading therefore gives a useful structural clue: it should not absorb the breath test or imply a gastroscopy. The Chinese gastrin source refers to various immunological methods; it does not name one precise assay platform.
The six Guangzhou panel-format pages explicitly print PGⅠ, PGⅡ and G17, but attach the qualification “Listed as a group. Individual sub-indicators are not fully specified.” Preserve the printed abbreviations and that note together. The source supports those names while leaving the complete local specification open. It does not authorise filling in additional components, report calculations or a particular method.
Two named pepsinogens do not confirm a reported ratio
A ratio is a separate reporting detail. The NCI review distinguishes PGI, PGII and the PGI:PGII ratio. None of these 17 package tables expressly says that the ratio is reported. Listing both measurements therefore leaves an administrative question: does the selected laboratory supply the two individual results, the calculated ratio, or both?
Do not answer that question by calculating a result from a package title or by adding a ratio to the promised scope. Ask for the actual report fields in the provider's specification. If a written request already names a ratio, keep that requested field unresolved until it is expressly matched.
Specimen and method also need their own confirmation. The NCI review discusses serum pepsinogen, and Mayo Clinic Laboratories' pepsinogen I notice specifies serum for that particular referral test. These sources explain a test context; they do not verify the specimen, assay, preparation or turnaround of the Chinese packages. None of the pepsinogen item labels in this sample supplies those details.
Keep the limits visible without interpreting a result
The NCI evidence review describes important limitations of serum-pepsinogen screening, including a lack of standard cut-off values. Its discussion of screening benefit also has a stated population context. It is not a universal Chinese screening guideline or a reason to select one of these packages. This guide therefore provides no threshold, risk category or screening schedule. NCI: stomach-screening evidence.
A pepsinogen entry cannot be used here as evidence of cancer clearance or as permission to replace an already requested endoscopy. An H. pylori test retains its own purpose and preparation questions. For a worked breath-test package example, use the Sanya C13 H. pylori guide; it does not settle any of the pepsinogen specifications above.
A request card that separates the outputs
Scroll horizontally to see all columns.
| Field | What the provider should identify |
|---|---|
| Package and source wording | Exact URL, page name and the copied pepsinogen row |
| Pepsinogen I and II | Full local names, individual report fields and specimen |
| Ratio, if already requested | Whether it is explicitly reported, or still unconfirmed |
| Gastrin | Exact form and method, without upgrading “Gastrin” to a more specific name by assumption |
| H. pylori test | Its separate exact name and preparation instructions |
| Endoscopy, if already requested | A separately confirmed procedure; do not infer it from a gastric-laboratory heading |
| Changes to the scope | Dated confirmation and any separate quote |
Suggested wording: “Please match my existing request to [package and link]. Confirm the full pepsinogen names, specimen and report fields, including whether a ratio is reported if requested. Preserve the exact gastrin wording. Please identify the H. pylori test and any requested endoscopy separately, and leave unresolved items marked as unconfirmed.”
The card helps obtain a precise specification; it is not a list of tests to request as a bundle. For a new symptom, a previous result or a decision about testing, the clinical question needs its own healthcare assessment. For catalogue clarification, begin with the package link through China check-up planning.
Sources and scope
Seventeen complete operator item tables were checked on 13 October 2026. The row-level comparison retains combined names, separate names, bilingual source text, group notes and missing specifications. NCI, MedlinePlus, NIDDK and Mayo supply general background only. No hospital-confirmed availability, diagnosis or clinician review is claimed.
