Scoring Rubric

Analytical report evaluation methodology

Methodology v4.1
RV Score = (Testing × 0.40) + (Label × 0.30) + (Custody × 0.20) + (CI × 0.10)

Testing Protocol 40%

Depth and scope of analytical testing performed.

Purity Scoring

Purity Range Points
≥99.5% 4.0
99.0 – 99.49% 3.5
98.0 – 98.99% 3.0
<98.0% 2.0

Additional Tests

Test Points Detection
MS Confirmation +3 Molecular identity
Net Peptide Content +2 Active compound vs. salts/moisture
Sterility +1 Microbial contamination
Endotoxin (LAL) +1 Bacterial endotoxins

Maximum 11 points → normalized to 10

Label Alignment 30%

Correlation between labeled claims and analytical results.

Element Points Criteria
Product Name 3 Compound identification matches label
Quantity Accuracy 0–4 Asymmetric scoring (see below)
Batch ID 2 Batch/lot number documented
Expiration 1 Expiration or retest date present

Quantity Variance Scoring

Variance Points
Overfill (any %) 4
0% to −5% 4
−5% to −10% 2
−10% to −15% 1
>−15% 0
Asymmetric Logic: Overfill may indicate NPC compensation. Underfill represents material shortfall.

Chain of Custody 20%

Documentation and sample handling verification.

Element Points
Batch ID present 15
Single vial tested 15
Two vials tested 25
Three+ vials tested 35
Receiving date documented 15
Tamper-evident seal 15
Lab custody seal 20

Maximum 115 points → normalized to 10

Conformance Index 10%

Data anomaly detection. 73 indicators evaluated.

Sample Indicators

Indicator Penalty
Purity >100% −20
Purity = 100.000% −8
Round number (.000 or .500) −3
Email as vendor identifier −5
Content >150% of label −8

Index Ranges

Score Classification
