Lactate Pyruvate Ratio
Screen lactate/pyruvate redox proxy with a caller-supplied threshold.
Description
Lactate/pyruvate screening compares a concentration ratio with a supplied threshold.
Lactate/pyruvate screening compares a concentration ratio with a supplied threshold. Interpretation requires matching measurement and compartment context.1
Screen lactate/pyruvate redox proxy with a caller-supplied threshold.
When to use Lactate Pyruvate Ratio
Use this tool to screen lactate/pyruvate redox proxy with a caller-supplied threshold.
Prepare the measured profile, formula counts, upstream model outputs or caller-defined reference criteria requested. Keep paired entries aligned and units, sample basis and preprocessing consistent.
How to use Lactate Pyruvate Ratio and understand its results
- Prepare the measured profile, formula counts, upstream model outputs or caller-defined reference criteria requested. Keep paired entries aligned and units, sample basis and preprocessing consistent.
- Enter lactate, pyruvate, minimumRatio using the field table and calculation rules, then run the tool.
- Read lactatePyruvateRatio, elevated. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| lactate | Lactate | number | Required |
| pyruvate | Pyruvate | number | Required |
| minimumRatio | Minimum ratio | number | Required |
Enter nonnegative lactate, positive pyruvate and finite threshold using a compatible concentration basis. Return ratio and inclusive elevated flag.
ratio=lactate/pyruvate; elevated=ratio≥threshold Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| lactatePyruvateRatio | Lactate pyruvate ratio | number |
| elevated | Elevated | boolean |

}Limitations and assumptions
No clinical reference range or redox potential is supplied. The threshold can be negative; the flag does not diagnose disease.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use NADH NAD Redox Index: Compare cellular NADH/NAD+ log10 ratio to a supplied reference. For a complementary task, use Lactate Glucose Yield: Compute apparent lactate yield per glucose and two-lactate carbon recovery.
