Part 3 of 6 in the "always tired" series; the other five are listed at the foot.
"My practitioner says I have 血虚, but my report is normal." It is the most common local misunderstanding, and nobody has got anything wrong — the two ideas simply sit too close together.
This part sets the two sides down side by side. Two starting points: blood deficiency (血虚) in TCM theory is described by the WHO's TCM terminology standard as a pathological state in which deficient blood fails to nourish the zang-fu organs and meridians; anaemia on a report is a haemoglobin value below the WHO's cutoff for your age and sex (part 1).
The short version
- The standard defines a pattern as a pathological summarization of the picture in a certain stage — those four words are the key.
- So a pattern name is the result of sorting, not the cause.
- In the standard's own architecture, the two entries whose English headword is "anaemia" both sit in the disorders part; the blood deficiency pattern sits among the patterns.
- So a normal report can still be placed under the pattern, and a low number need not be — both of those are this article's inferences.
- Hearing 「血虚」 does not mean buying iron tablets at the pharmacy on your own: the WHO's line is that supplements are taken if a qualified health-care provider recommends them.
First, the things that cannot wait
Weight loss you did not intend, or breathlessness, palpitations or chest tightness alongside it — see a doctor for investigation first. The NHS states each separately: it is important to get it checked if you are losing weight without trying, and sometimes the cause can be cancer; and palpitations can be caused by a condition such as iron deficiency anaemia or an overactive thyroid (hyperthyroidism).
Persistently low mood, loss of interest, or thoughts of harming yourself — call 999 now, or go to the nearest hospital emergency department. To talk to someone, the Ministry of Health's Talian HEAL 15555 is open every day from 8 am to 12 midnight, public holidays included [KKM-HEAL]; Befrienders KL is open 24 hours on 03-7627 2929 [BEF]. You can also contact your doctor.
The full list, and the reason for each, are in part 5. TCM and Western medicine complement each other; it is not a choice between them.
A note: this section is general information only. For conditions like these, follow your doctor's diagnosis and treatment, and seek medical attention when you need it.
I. Why a pattern name is a category, not a cause
The standard's definition of a pattern (证) is: a pathological summarization on the disease location, etiological factors, nature, severity and prognosis in a certain stage.
Its definition of pattern identification (辨证) is: the process of an overall analysis of clinical data to determine the location, etiological factors and nature of a disease at a certain stage.
Both definitions carry the words "in a certain stage". A pattern name is the practitioner's summary of the whole picture at that time; when the stage changes, the category can change. "Blood deficiency pattern" tells you the conclusion of that summary — deficiency, of blood — not the thing that caused the tiredness.
The standard's own wording works the same way: its description of the blood deficiency pattern ends with "often occurs when blood fails to nourish the zang-fu organs, meridians and other body tissues" — which shows a pattern has causes upstream of it. The name is the result of the sorting, not the cause itself. On how assessment works: what pattern differentiation is.
💡 Remember: a pattern name answers "how do we summarise the picture at this stage", not "what caused this".
II. How the standard files things: diseases on one side, patterns on the other
This is the step that settles it, because the answer is in the standard's table of contents rather than in anyone's opinion.
The standard defines a disease (病) as: the whole process of struggle between anti-pathogenic qi and pathogenic factors, yin–yang imbalance and progression, manifesting as specific symptoms and patterns; in a narrow sense, a disease has its specific name.
Then look at where it puts the entries. The two entries whose English headword is "anaemia" both sit in the part the standard calls Disorders — 「疾病」 in its Chinese column — one of them is 「萎黄病」, whose English column reads iron deficiency anaemia, listed under spleen-system diseases; the other sits under disorders of qi, blood and bodily fluids. The blood deficiency pattern (血虚证) sits in the patterns part.
One is a disease name, the other a pattern name — in the standard's own architecture they were never on the same axis.

III. Two instruments, measuring different things
Now the blood-report side. The WHO's anaemia fact sheet puts anaemia on a threshold, and treats it as a symptom of an underlying condition.
The sourcing, stated once: the table's left column is all from the WHO's 2022 TCM terminology standard; the right column is from the WHO's anaemia fact sheet and the same body's 2024 haemoglobin-cutoff guideline.
| 「血虚证」 in TCM theory | "Anaemia" on a blood report | |
|---|---|---|
| What it is | A pattern: a pathological summarization of location, etiological factors and nature at a certain stage | A condition: haemoglobin concentration below a threshold set by age, sex and physiological status |
| How it is decided | Pattern identification — an overall analysis of clinical data; the practitioner's judgement | A blood test — the number against the cutoff: nonpregnant adult women below 120 g/L, men below 130 g/L; the doctor's reading |
| What the name tells you | The conclusion of the sorting: deficiency, of blood — where 「血」 means the function of moistening and nourishing the body | A measurement; the fact sheet treats it as a symptom of an underlying condition — the next step is finding the cause |
Set the two definitions side by side and two sentences follow. Both are this article's inferences from the definitions, not either source's words.
The haemoglobin on the report can be normal and the practitioner may still place the picture under the blood deficiency pattern — because that category is not defined by a number.
The number can be below the cutoff and the practitioner may not place it under the blood deficiency pattern — because the two entries whose English headword is "anaemia" sit in the standard's disorders part, not among the patterns.
Neither side is wrong; they are two instruments measuring different things.
What changes is what you do. Hearing 「血虚」 does not mean buying iron tablets at the pharmacy on your own — the WHO fact sheet's line is that supplements are taken if a qualified health-care provider recommends them. In this article's terms, that is the doctor who has seen the blood report.
And a normal report does not mean the TCM consultation has nothing to discuss.
A note: this section is general information only. For conditions like these, follow your doctor's diagnosis and treatment, and seek medical attention when you need it.
The words in this part
All four come from the WHO's TCM terminology standard.
- Pattern (证) — a pathological summarization of the disease location, etiological factors, nature, severity and prognosis in a certain stage. When a practitioner says 「证」 at a consultation, this is what it means.
- Pattern identification (辨证) — the process of an overall analysis of clinical data to determine a disease's location, etiological factors and nature. It is the process; the pattern is the result.
- Disease (病) — the whole process of struggle between anti-pathogenic qi and pathogenic factors, yin–yang imbalance and progression; in a narrow sense, a disease has its specific name.
- Blood deficiency pattern (血虚证) — the pattern name the standard files among the patterns; its description mentions it often occurs when blood fails to nourish the zang-fu organs, meridians and other body tissues.
Frequently asked
My report is normal and my practitioner says 血虚 — is that a contradiction? It is not a contradiction, and it is not a confirmation either — the two sides are not measuring the same thing (section III). What to actually do is tell both sides: take the report to the consultation, and take what you hear at the consultation back to your doctor.
Hearing 「血虚」 — should I buy iron tablets first? Do not buy them on your own. The WHO's line is that supplements are taken if a qualified health-care provider recommends them; whether iron is needed is decided by the doctor who has seen your blood report. And never stop prescribed medication on your own because you are going to see a TCM practitioner.

👉 If you are not sure whether a normal report means there is still anything to discuss with a TCM practitioner, you are welcome to book an online consultation with HansMed, where a practitioner registered under the T&CM Act 2016 can assess it with you; if anything in "First, the things that cannot wait" above or in part 5 applies, see a doctor first.
