Alligation Alternate Two Stock Calculator
Alligation alternate ideal two-stock SAME mass-basis strength/mass target, not volumetric contraction, product compatibility, sterility or compounding authorization.
Description
Ideal two-stock alligation balances component mass to reach a specified fraction between two distinct stock strengths.
Ideal two-stock alligation balances component mass to reach a specified fraction between two distinct stock strengths.1
This tool returns the conditional low- and high-stock masses on that common mass basis, without establishing compatibility or a preparation process.
When to use Alligation Alternate Two Stock Calculator
This tool returns the conditional low- and high-stock masses on that common mass basis, without establishing compatibility or a preparation process.
How to use Alligation Alternate Two Stock Calculator and how it works
- Prepare verified low stock strength fraction, verified high stock strength fraction, specified final strength fraction, specified final total mass grams, using the input definitions and matching units below.
- Enter the required fields and run Alligation Alternate Two Stock Calculator.
- Read result.conditionalLowStockMassGrams, result.conditionalHighStockMassGrams using the units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedLowStockStrengthFraction | Caller Verified Low Stock Strength Fraction. Use the units and matching context stated in the calculation below. | number | Required; finite; other constraints below |
| callerVerifiedHighStockStrengthFraction | Caller Verified High Stock Strength Fraction. Use the units and matching context stated in the calculation below. | number | Required; finite; other constraints below |
| callerSpecifiedFinalStrengthFraction | Caller Specified Final Strength Fraction. Use the units and matching context stated in the calculation below. | number | Required; finite; other constraints below |
| callerSpecifiedFinalTotalMassGrams | Caller Specified Final Total Mass Grams. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Require three fractions from 0 to 1 and positive final total grams. High-stock strength must exceed low-stock strength and target must lie inclusively between them. Calculate high-stock mass as total times (target-low)/(high-low), and low-stock mass as the remaining total. Endpoint targets may give zero of one stock. This is an ideal same-mass-basis balance without compatibility or volume-contraction assessment.
highGrams=totalGrams*(target-low)/(high-low); lowGrams=totalGrams-highGrams Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.conditionalLowStockMassGrams | Ideal low-stock mass in grams under the common mass-basis balance. | number |
| result.conditionalHighStockMassGrams | Ideal high-stock mass in grams under the common mass-basis balance. | number |

}Limitations and assumptions
Patient context, drug formulation, route, sampling time, assay units and applicable clinician-verified protocol must be independently established. The output supplies no dosing, titration, switching or administration instruction.
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
