Albumin Variants Plasma-Derived Product Quality Checker — Human Albumin Variant Control

ℹ️ Utility checks the profile of variants and aggregates of human albumin (CE/HPLC):
• Main peak (monomers): ≥95.0%
• Pre-albumin (fast variants): ≤2.0%
• Post-albumin (slow variants): ≤2.0%
• Dimers: ≤1.0%
• Polymers/Aggregates: ≤0.5%
• Total Purity: ≥96.0%
• Endotoxins: ≤0.5 EU/mg

⚠️ CRITICAL: High level of aggregates (dimers/polymers) increases risk of anaphylactoid reactions.
Changes in variant profile may indicate oxidation or glycation during storage.

Input format:
BatchNumber,AlbuminMainPeakPercent,PreAlbuminPercent,PostAlbuminPercent,DimerPercent,PolymerPercent,ProteinConcentrationGPerL,PurityPercent,EndotoxinsEUPerMg

— WHY IS THIS NEEDED?
Human albumin is an important plasma protein used for treating hypoalbuminemia and shock:
• Derived from pooled human plasma
• Subject to post-translational modifications (oxidation, glycation, deamidation)
• Prone to forming dimers and polymers under stress (temperature, pH)
• Albumin aggregates can cause immune reactions in patients

⚠️ CRITICAL:
• Main peak (monomers) must be ≥95.0% — guarantee of native protein structure
• Dimers and polymers ≤1.5% total — critical for safety (anaphylaxis risk)
• Variants (pre/post) reflect chemical stability of the molecule
• Endotoxins strictly controlled due to blood plasma origin
• Total purity ≥96.0% ensures absence of other plasma proteins

Key features:
• Analysis of albumin variants by Capillary Electrophoresis (CE) or HPLC
• Separation into monomers, dimers, and high-molecular-weight aggregates
• Control of oxidized and glycated forms (fast/slow peaks)
• Safety assessment of plasma-derived product

Critical parameters:
• Main Albumin Peak: ≥95.0%
• Pre-Albumin Variants: ≤2.0%
• Post-Albumin Variants: ≤2.0%
• Dimer Content: ≤1.0%
• Polymer/Aggregates: ≤0.5%
• Total Purity: ≥96.0%
• Endotoxins: ≤0.5 EU/mg

💡 Usage tips:
1. CE-SDS or SEC-HPLC method is the gold standard for aggregate analysis
2. Pre-albumin peaks often correspond to oxidized methionine forms
3. Post-albumin peaks may be related to glycation or free thiols
4. Storage at 2-8°C is critical to prevent dimer formation
5. If high aggregates detected, check pasteurization and filtration conditions

⚠️ Note: Albumin is not a single molecule but a family of close variants. However, for therapeutic use, it is critical to maintain the native monomeric form. Aggregation is an irreversible process that cannot be corrected by purification at the final stage, so control at the finished product stage is mandatory.

OQ-001	Valid sample row from input.csv.	PASS or acceptable WARNING according to rules.
OQ-002	Remove a mandatory CSV column.	Schema error or FAIL with missing-column reference.
OQ-003	Place a non-numeric value into a numeric field.	Type-conversion error with row/field reference.
OQ-004	Set a critical parameter outside the limit.	FAIL and critical finding.
OQ-005	Verify output.json structure.	All mandatory sections are present and JSON is valid.
OQ-006	Verify batch/sample traceability.	Input and result identifiers match.
OQ-007	Verify fallback/decomposition for combined APIs.	Component checks are explicitly documented.
PQ-001	Verify 3–5 real user batches/samples.	Result is confirmed by QC/QA review.
PQ-002	Verify deviation workflow and manual QA decision.	Utility supports review but does not replace approved decision.

QA/QC and change control

Do not rename columns without updating validator, documentation and test set.
Retain input.csv, output.json, executable version and checksum.
Before production use, perform IQ/OQ/PQ or equivalent CSV/CSA verification.
Critical limits shall be verified against the approved specification, registration dossier and local SOPs.
For combination products, document whether the specialized FDC utility or fallback component checks were used.
The utility provides structured QC decision support; final release decision remains with QA/QP and approved procedures.
