No
The device is described as a general-purpose laboratory instrument for in vitro diagnostic use, used to prepare samples for analysis, not to treat a condition.
No
The device is described as a "general-purpose laboratory instrument" and an "automated sample-handling instrument" that prepares samples for analysis by other devices. While the prepared samples are for "in vitro diagnostic use," the AutoPrep System itself performs sample processing, not diagnosis. This system delivers an enriched, processed sample that is ready to analyze by other flow cytometers, fluorescent microscopes or CellTracks Analyzer, etc., and does not do the analysis itself.
No
The device description clearly outlines a physical instrument ("automated sample-handling instrument") that performs mechanical and chemical processes on whole blood samples. It involves the addition of reagents, magnetic separation, aspiration, and resuspension, all of which are hardware-dependent functions. While software likely controls these processes, the device itself is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section explicitly states: "The system is for in vitro diagnostic use."
- Intended Use: The intended use describes the system as a "general-purpose laboratory instrument used with immunomagnetic reagents that capture and enrich target cells, and labeling reagents that differentiate cells in whole blood." This clearly indicates it's used to analyze biological samples (whole blood) outside of the body for diagnostic purposes.
- Device Description: The device description details how the system processes whole blood samples using reagents to isolate and label specific cells for subsequent analysis by other instruments. This process is characteristic of in vitro diagnostic procedures.
- Clinical Trial: The summary of performance studies mentions a "Clinical trial" and testing performed at "clinical sites" by "Medical or Laboratory Technicians." This further supports its use in a clinical diagnostic setting.

Intended Use / Indications for Use
The intended use for the Immunicon CellTracks™ AutoPrep System is as a generalpurpose laboratory instrument used with immunomagnetic reagents that capture and enrich target cells, and labeling reagents that differentiate cells in whole blood. Cell analyzers such as the CellTracks™ Analyzer, CellSpotter™ System, flow cytometers or microscopes may be used for cell identification and enumeration. The system is for in vitro diagnostic use.

Device Description
The CellTracks™ AutoPrep System is an automated sample-handling instrument that starts with a tube of anticoagulated whole blood and delivers an enriched, processed sample that is ready to analyze by flow-cytometry, fluorescent microscopy, CellSpotter™ System or by the CellTracks™ Analyzer. The AutoPrep System performs several steps, including red cell detection, plasma aspiration and filling of a sample chamber or test tube. The principal of operation relates to the addition of a ferrofluid, which has been conjugated with monoclonal antibodies that act with the system to magnetically separate the cells of interest and in subsequent steps, within the system, to add fluorescencelabeled monoclonals to further differentiate the captured cells. The first reagent added is ferrofluid, which consists of a magnetic core surrounded by a protein layer coated with antibodies for attachment to cells. Ferrofluid particles are colloidal and when mixed with a sample containing the target cells, they interact and attach to the target cells. The ferrofluid/sample mixture is placed in a strong magnetic field, which causes the labeled target cells to move to the side of the tube. The blood is aspirated, the magnetic field is removed and the cells are resuspended in a small volume of buffer and fluorescent reagents are added for the identification and enumeration of the target cells. Another magnetic separation step and resuspension is performed and the sample is now ready for analysis. The immunomagnetic enrichment process is the new technology but does not raise any new issues of safety and effectiveness.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical testing: Medical or Laboratory Technicians performed clinical testing at three clinical sites. The Clinical trial consisted of performing a 20 day precision study according to NCCLS "EP5-A Evaluation of Precision Performance of Clinical Chemistry Devices; Approved Guideline". The Clinical trial indicated that the CellTracks™ AutoPrep System was capable of removing small numbers of control cells reproducibly from 7.5 ml of whole blood (38 cell spike level CV = 16.8, 264 spike level CV = 11.72).
Nonclinical testing: Nonclinical testing indicated a sensitivity of being able to recover cells at very low levels at approximately one cell per a 7.5 ml volume of whole blood and a linear recovery range from 2 to 906 cells with a slope of 1.0221 and an r = 0.9946. A method comparison was performed comparing the AutoPrep system to the predicate device according to NCCLS "EP9-A Method Comparison and Bias Estimation Using Patient Samples; Approved Guideline" The results of the comparison showed a correlation coefficient of 0.99, a slope of 1.0935 with an intercept of 4.0344 and an r of 0.9801.

Dear Mr. Scott:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
