The operator identifies and verifies the suggested classification of each cell according to type. DM96 is intended to be used by skilled operators, trained in the use of the device and in recognition of blood cells.
Device Description
DM96 is an automated cell-locating device for differential count of white blood cells, characterization of red blood cell morphology and platelet estimation. DM96 consists of a slidescanning unit (a slide feeder, a microscope and a camera) and a computer system containing the acquisition and classification software "CellaVision Blood Differential software".
More Information

Not Found

Yes
The summary explicitly states that "Cell images are analyzed using standard mathematical methods, including deterministic artificial neural networks (ANN's) trained to distinguish between classes of white blood cells." Artificial Neural Networks are a type of machine learning algorithm.

No.
The device is used for locating blood cells on smears and assisting in their classification, which is a diagnostic function, not a therapeutic one.

Yes

The device aids in the differential count of white blood cells and characterization of red blood cell morphology on peripheral blood smears, which are diagnostic activities. The 'Intended Use' and 'Device Description' sections both state its purpose as an "automated cell-locating device for differential count of white blood cells, characterization of red blood cell morphology and platelet estimation," which are steps in diagnosing various hematological conditions.

No

The device description explicitly states that the DM96 consists of a "slidescanning unit (a slide feeder, a microscope and a camera)" in addition to the computer system and software. This indicates the presence of hardware components beyond just software.

Based on the provided information, yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The device is intended to be used on "peripheral blood smears" to "automatically locates and presents images of blood cells" for the operator to "identify and verify the suggested classification of each cell according to type." This directly involves the examination of biological specimens (blood) outside of the body to provide information for diagnostic purposes (differential count of white blood cells, characterization of red blood cell morphology and platelet estimation).
  • Device Description: It describes an "automated cell-locating device for differential count of white blood cells, characterization of red blood cell morphology and platelet estimation." These are all diagnostic tests performed on blood samples.
  • Anatomical Site: "peripheral blood smears" confirms the use of a biological sample.
  • Clinical Evaluation: The description mentions a "clinical evaluation" performed to confirm "equivalence with the predicate method DiffMaster Octavia™ for differentiation of white blood cells." This type of evaluation is standard for IVD devices to demonstrate their performance for diagnostic use.
  • Key Metrics: The mention of "clinical sensitivity and specificity" are key performance metrics used to evaluate the accuracy and reliability of diagnostic tests.
  • Predicate Device: The predicate device, K003301 DiffMaster Octavia™ Hematology Analyzer, is also a device used for analyzing blood cells, which falls under the category of IVDs.

The device's function of analyzing blood cells from a peripheral blood smear to provide information about cell types and morphology for diagnostic purposes clearly aligns with the definition of an In Vitro Diagnostic device.

No
The letter does not state that the FDA has reviewed and approved or cleared a PCCP for this specific device.

5. Technological characteristics, comparison to predicate device

Like the predicate device, DM96 locates white blood cells, stores digital images of the cells and displays the images in an organized manner and suggests a cell class for each cell to aid operators in performing the differential count procedure. A competent operator is required to confirm or modify the suggested classification of each cell. It is intended to be used by skilled operators, trained in the use of the device and in recognition of blood cells. Like the predicate device, DM96 presents an overview image from which it is possible to characterize red blood cells regarding size, shape and color. In addition, the DM96 presents an overview image and facilitates platelet estimation.

Brief discussion of non-clinical factors supporting a determination of substantial equivalence: The method requires a competent human examiner to review the microscopic images of the cells as does the predicate method and device. See substantial equivalence comparisons below.
