Indications for Use
BD Vacutainer® Fluoride Blood Collection Tubes are evacuated, sterile, single use, in vitro diagnostic medical devices available with Sodium Fluoride/Potassium Oxalate or Sodium Fluoride/Na2EDTA. They are intended to be used by trained healthcare professionals for the collection, containment, preservation, transportation, and centrifugation of venous blood specimens as required for in vitro diagnostic testing. Plastic BD Vacutainer® Fluoride Blood Collection Tubes are used to collect whole blood for the generation of plasma samples. Blood collected in BD Vacutainer® Fluoride Blood Collection Tubes containing Sodium Fluoride/Potassium Oxalate are used for glucose and lactate determinations. Blood collected in BD Vacutainer® Fluoride Blood Collection Tubes containing Sodium Fluoride/Na2EDTA are used for glucose determinations.
Device Story
Evacuated, sterile, single-use plastic tubes; used by trained healthcare professionals in clinical settings for venous blood collection. Tubes contain blended powder additives (Sodium Fluoride/Potassium Oxalate or Sodium Fluoride/Na2EDTA) to provide anticoagulation and antiglycolytic preservation. Operation involves insertion into standard needle holder; vacuum-driven blood draw; manual inversion for mixing; centrifugation at 2000 RCF. Output is plasma sample for clinical laboratory testing. Facilitates accurate glucose and lactate determination by preserving sample integrity during transport and processing.
Clinical Evidence
No clinical trials; performance established via bench testing and method comparison studies. Precision studies (N=25 for glucose, N=40 for lactate) demonstrated acceptable repeatability and reproducibility. Method comparison against cleared comparator tubes (N=83-137 samples) showed high correlation (r=0.99-1.0) for glucose and lactate across two instrument platforms. Stability studies confirmed glucose stability up to 24 hours (refrigerated) and lactate up to 45 minutes (on ice).
Technological Characteristics
Plastic tubes (13x75mm, 13x100mm); Hemogard™ safety closure; silicone-lubricated stoppers. Additives: Sodium Fluoride (antiglycolytic), Potassium Oxalate or Na2EDTA (anticoagulants). Vacuum-based draw mechanism. Sterilization via radiation (ISO 11137). Complies with CLSI GP39-A6 and CLSI EP25-A standards.
Indications for Use
Indicated for use by trained healthcare professionals for venous blood collection, containment, preservation, transportation, and centrifugation to generate plasma samples for glucose and lactate diagnostic testing.

IV Device/System Characteristics:
A Device Description:
K231237 - Page 2 of 8
{2}
The BD Vacutainer® Fluoride Blood Collection Tubes are evacuated, sterile, single use tubes intended to be used in settings where venous blood samples would be collected by trained healthcare professionals for the collection, containment, preservation, transportation, and centrifugation of blood in a closed tube.
BD Vacutainer® Fluoride Blood Collection Tubes are available in plastic 13 x 75mm and 13 x 100mm configurations with draw volumes from 2.0 to 6 mL. The configurations contain various additive combinations in a blended powder mixture, including the additives Potassium Oxalate (kOx) and Na₂-EDTA which provide an anticoagulated specimen when used according to the instructions for use. The tubes containing Na₂-EDTA can be used to produce plasma samples to measure glucose. The tubes containing kOx can be used to produce plasma samples to measure glucose or lactate. The blended powder mixture contains sodium fluoride (NaF), which acts as an antiglycolytic agent. Tubes include a gray color-coded BD Hemogard™ Closure indicative of the NaF additive. Tube stoppers are lubricated with silicone to facilitate stopper insertion.
## B Principle of Operation:
The BD Vacutainer® Fluoride Blood Collection Tubes are intended to be placed inside any BD Vacutainer® Needle Holder of the standard size or an adapter of a blood collection system. Once the vein of the patient has been penetrated using a standard needle, center the collection tube in the holder and push the tube fully onto the needle, puncturing the stopper of the tube. The tube uses a controlled vacuum to pull a specific volume of blood into the sterile interior of the tube. Once the pressure is equalized, the blood flow ceases, and the tube is removed from the needle holder or needle. Immediately after the blood has been drawn, the tube is gently inverted 8 times to mix the blood with the anticoagulant and antiglycolytic. The BD Vacutainer® Fluoride Blood Collection Tubes are centrifuged at 2000 RCF (relative centrifuge force or g's). The whole blood is then processed to plasma for various clinical laboratory testing.

## VII Performance Characteristics (if/when applicable):
## A Analytical Performance:
### 1. Precision/Reproducibility:
Two studies were conducted to evaluate the repeatability (within-tube), lot-to-lot (between lots), and tube-to-tube (between tube) variation in the BD Vacutainer® Fluoride Blood Collection Tubes. Sodium Fluoride/ Potassium Oxalate (NaF/KOx) tubes were tested and evaluated using glucose and lactate, and Sodium Fluoride EDTA (NaF/Na₂EDTA) tubes were tested and evaluated using glucose. The study designs included subjects from the clinical settings. Three lots of each of the BD Vacutainer® Fluoride Blood Collection Tubes (candidate device) were used in the study. The study was performed using samples collected from 25 subjects for glucose and 40 subjects for lactate, and all samples were run in duplicate on two instrument platforms. One representative platform with precision results is summarized in the tables below:

## 5. Traceability, Stability, Expected Values (Controls, Calibrators, or Methods):
### A. Within-Tube Stability (sample stability):
Glucose (GLU) and lactate stability studies were conducted to assess within-tube stability for BD Vacutainer® Fluoride Blood Collection tubes using NaF/ $\mathrm{Na_2EDTA}$ 13x75 2mL tubes for glucose determinations and NaF/KOx 13x75 4mL for glucose and lactate determinations. Stability studies were assessed for glucose up to 24hr. Lactate studies were assessed up to 45 minutes while the samples were stored in tubes on ice, followed by refrigerated storage and centrifugation. Analyte stability was tested on a minimum of two instrument platforms. The study protocols and acceptance criteria have been reviewed and found to be acceptable. These studies support the storage of samples for measurement of lactate up to 45 minutes when held on ice and glucose up to 4 hours at room temperature or 24 hours when refrigerated.
### B. Shelf-Life
Real Time stability testing of the BD Vacutainer® Fluoride Blood Collection tubes showed that the candidate device is stable for 15-16 months when stored at 4 to $25^{\circ}\mathrm{C}$ . The stability study protocol and acceptance criteria has been reviewed and found to be acceptable. The claimed shelf-life of each tube is shown below:
| Fluoride Blood Tube | Claimed Shelf-life | Volume |
| --- | --- | --- |
| NaF/Na2EDTA | 16 months | 2 mL |
| NaF/KOx | 15 months | 2 mL |
| NaF/KOx | 16 months | 4 mL |
| NaF/KOx | 15 months | 6 mL |
### C. Additional bench testing on the candidate device
Benchtop studies were conducted to assess draw volume, X-value, 2nd stopper pullout, stopper/shield separation, stopper leakage, tube leakage, breakage resistance during drop testing, breakage resistance during centrifugation testing, barrier formation and packaging performance during shipping and handling. The study protocols were reviewed, and performance was considered acceptable.

3. Other Clinical Supportive Data (When 1. and 2. Are Not Applicable):
A study was conducted to evaluate equivalence between the BD Vacutainer® Fluoride Blood Collection Tubes (6 mL BD Vacutainer® Sodium Fluoride / Potassium Oxalate and 2 mL BD Vacutainer® Sodium Fluoride / Na2EDTA) and a cleared comparator tube (NaF/K Oxalate Blood Collection Tubes, 2 mL) for testing glucose and lactate. All samples were collected by routine venipuncture using standard phlebotomy techniques. In addition, contrived samples were prepared to obtain results that spanned the analytical measurement range for the tested analytes. Glucose and Lactate were evaluated on two instrument platforms each and demonstrated comparable results between the candidate tubes and the comparator tubes.
Immediately after collection and prior to centrifugation, tubes were inspected for complete fill, clot formation and stopper leakage. After centrifugation, additional visual assessments were performed. Tubes were then handled and processed according to manufacturer's recommended handling conditions for tube inversions and centrifugation time and force. Biases between tube types were estimated with 95% confidence intervals. Regression analyses for a representative tube using each instrument platform are provided in the tables below:
