🤰 HELLP Criteria (Tennessee)
UseWhen to use: preeclampsia-spectrum illness with suspected microangiopathic liver injury.
Strata3/3 = complete; 1–2 = partial — both need urgent OB pathways.
LimitsWhen not to use: outside pregnancy/early postpartum without obstetric… · Pitfall: missing AFLP/TTP/HUS mimics. · Mississippi classes further stratify by platelet count.

Methodology · worked example, guidelines & full notes
Three lab pillars.
When to use
When to use: preeclampsia-spectrum illness with suspected microangiopathic liver injury.
How it works
Complete HELLP: platelets ≤100×10⁹/L + AST ≥70 IU/L + LDH ≥600 IU/L.
Key points
- Three lab pillars.
- Partial still matters.
- Next: OB critical care / delivery planning.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Platelets ≤ 100×10⁹/L | No |
|---|---|
| AST ≥ 70 IU/L | No |
| LDH ≥ 600 IU/L (hemolysis marker) | No |
| Clinical context | Pregnant or ≤7 days postpartum with suspected preeclampsia spectrum |
→HELLPCriteria not met

FAQ
Frequently asked questions
- Does HELLP Criteria (Tennessee) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is HELLP Criteria (Tennessee) calculated in practice? Can you show a worked example?
- Inputs: Platelets ≤ 100×10⁹/L No, AST ≥ 70 IU/L No, LDH ≥ 600 IU/L (hemolysis marker) No, Clinical context Pregnant or ≤7 days postpartum with suspected preeclampsia spectrum → Result: HELLP Criteria not met（Cue: Does not meet Tennessee HELLP labs now） Inputs: Platelets ≤ 100×10⁹/L Yes, AST ≥ 70 IU/L Yes, LDH ≥ 600 IU/L (hemolysis marker) Yes, Clinical context Other / not applicable → Result: HELLP Context not met（Next: Reconsider differential (TTP/HUS/AFLP/sepsis)）
