### B Principle of Operation:
The BD Vacutainer Citrate Tubes are plastic, evacuated, and sterile (1.8 mL or 2.7 mL) tubes. The tubes contain a buffered sodium citrate used to anti-coagulate whole blood for hematological investigations. It acts as an extracorporeal anticoagulant by binding free calcium in the blood which is a necessary co-factor to several steps in the clotting/coagulation cascade. Anticoagulation with buffered sodium citrate is reversible with the addition of excess calcium.

## VII Performance Characteristics (if/when applicable):
## A Analytical Performance:
### 1. Precision/Reproducibility:
The study was conducted to evaluate the clinical performance of BD Vacutainer Citrate Tubes (2.7 mL) for repeatability (within-tube), lot-to-lot and tube-to-tube variation in comparison with Greiner Bio-One Vacuette Citrate Tubes (2.7 mL) for selected coagulation parameters (PT, INR, aPTT, D-Dimer, and Anti-Factor Xa). Blood from sixty-five subjects was collected into the study tubes, which consisted of three lots of each tube type. Samples were tested for the coagulation parameters within 4 hours of collection at room temperature on the STA Compact Max, Sysmex CS-2500 and Instrumentation Laboratory ACL TOP 750. Performance of the BD Vacutainer Citrate Tubes for between-lot variation and between-tube variation showed non inferiority for all tube comparisons for the coagulation parameters tested on instrument platforms when compared with the comparator device.

Shelf-Life Stability
Shelf-life stability studies were conducted by using BD Vacutainer Citrate Tubes at 7 months for $1.8\mathrm{mL}$ BD Citrate Tubes and at 10 months for $2.7\mathrm{mL}$ BD Citrate Tubes, respectively, comparing with BD Vacutainer Citrate Tubes that were near manufacture date (<30 days). The studies were conducted by testing selected routine coagulation parameters. Sixty-nine normal and abnormal samples (on anticoagulants) were included in this study. The results showed that the shelf-life for BD Citrate Tubes is 6 months $(1.8\mathrm{mL})$ and 9 months $(2.7\mathrm{mL})$ when stored at $4 - 25^{\circ}\mathrm{C}$ .
Within-Tube Stability
Within-tube stability was evaluated by using BD Vacutainer Citrate Tubes stored at room temperature for routine coagulation parameters PT/INR, aPTT, Anti-Factor Xa and D-Dimer. Sixty normal and abnormal (on anticoagulants) samples were tested at time zero (t0), 4 hours, 8 hours measuring Anti-Factor Xa, D-Dimer, PT/INR, and aPTT; Sixty-eight normal and abnormal (on anticoagulants) samples were tested at 0, 16, and 24 hours measuring D-Dimer, INR, and PT. The BD Vacutainer Citrate Tubes results showed clinical equivalence of within-tube stability for PT/INR at 24 hours, D-Dimer at 16 hours, and aPTT, Anti-Factor Xa at 8 hours. All analytes tested at every time point were tested at room temperature (15-25 °C).

B Comparison Studies:
1. Method Comparison with Predicate Device:
The method comparison study was conducted at five clinical sites including 219 participants with 18 years of age or older. Fresh venous whole blood was collected into BD Vacutainer Citrate Tubes (BD Citrate) and Greiner Bio-One Vacuette Citrated Tubes (Greiner Citrate). Samples were tested for representative tests including, Prothrombin Time with International Normalized Ratio (PT/INR), Activated Partial Thromboplastin Time (aPTT), D-Dimer, and Anti-Factor Xa. An additional tube (Greiner K2EDTA) for hematocrit was drawn for study eligibility. Participant populations included healthy/normal participants, patients on oral anticoagulant therapy, and patients on unfractionated heparin. The study was tested on two platforms (Diagnostica Stago STA Compact Max and Instrumentation Laboratory ACL TOP). For each analyte on each platform, Deming or Passing-Bablok regression was used to estimate average differences between the evaluation tube (BD Citrate) and comparator (Greiner Citrate) tubes at the medically relevant points for each analyte on each platform. The results are summarized in the following table:

3. Other Clinical Supportive Data (When 1. and 2. Are Not Applicable):
A. Draw Volume Performance
The draw volume study is conducted to demonstrate functional draw volume performance of BD Vacutainer Citrate tube products to confirm retention of vacuum by comparing the results from the control at time zero (t0) to time points over the claimed shelf-life. A sample size of n=90, evenly divided between each of the three product lots, was collected at each test interval for each sterilization dose and storage condition. The results showed that the BD Vacutainer Citrate Tubes (2.7 mL and 1.8 mL) met the draw volume acceptance criteria for all intervals of accelerated aging to support a shelf life of 6 months (1.8 mL) and 9 months (2.7 mL).
B. Breakage Resistance During Drop and Centrifugation Testing
This study is conducted to demonstrate functional breakage resistance performance during drop testing for plastic tubes and during centrifugation for plastic tubes.
Drop Breakage Resistance: The test article is filled, centrifuged, stored at frozen and refrigerated temperatures, and then dropped from a set height. Samples are subsequently inspected for breakage and leakage. A sample size of n=183, evenly divided between each of the three (3) product lots, was collected at each test interval for each sterilization dose and storage condition.

Centrifugation Breakage Resistance: The test article is filled, centrifuged, and subsequently inspected for breakage and leakage. A sample size of n=300, evenly divided between each of the three (3) product lots, was collected at each test interval for each sterilization dose and storage condition.
The results showed that the BD Vacutainer Citrate Blood Collection tubes (1.8 mL and 2.7 mL) met the drop and centrifugation breakage acceptance criteria to support the current claimed shelf life of 9 months for the BD Vacutainer 2.7 mL Citrate Blood Collection and 6 months for the BD Vacutainer 1.8 mL Citrate Blood Collection tube.
## C. Stopper Pullout
Stopper Pullout testing is to demonstrate functional stopper performance in the event that the stopper is removed from the tube to access the sample and then reinserted. 90 samples were measured for First Stopper Pullout Force, and n=90 samples were measured for Needle Withdrawal Force. Results demonstrate that the force holding the stopper in the tube is greater than the force required to remove the collection needle from the stopper during sample collection. Second Stopper Pullout testing is to demonstrate functional stopper performance in the event that the stopper is removed from the tube to access the sample and then reinserted. The tests confirmed the acceptance criteria was met.
## D. Ship Testing
Ship testing was performed to evaluate packaging efficacy and safety during simulated shipping and handling conditions. Shipping and handling were simulated for temperature fluctuations, vibrations during shipping, and dropping. A sample size of at least n=30 shelf packs, evenly divided between each of the three (3) product lots, was collected. The result demonstrated that all tubes (1.8 mL and 2.7 mL) met the Ship Testing acceptance criteria. Results indicated no occurrence of damage from Ship Testing.
