Intended Use
The Vital Scientific APTT is an in-vitro diagnostic reagent intended for use in a manual method in a clinical laboratory for the performance of Activated Partial Thromboplastin Time (APTT) testing for the detection of coagulation abnormalities in the intrinsic pathway.
Device Description
The APTT reagent is intended for use in determining activated partial thromboplastin time (APTT) and coagulation factor assays that are based on a modified APTT. The capacity of blood to form a fibrin clot by way of the intrinsic homeostatic pathway requires coagulation factors XII, XI, IX, VIII, platelet lipids and calcium. The assay is performed by the addition of a suspension of rabbit brain cephalin with a surface activator.
More Information

No
The summary describes a reagent for a standard laboratory test and does not mention any AI or ML components.

No
This device is an in-vitro diagnostic reagent used for Activated Partial Thromboplastin Time (APTT) testing to detect coagulation abnormalities. It is used for diagnostic purposes, not for treating any condition.

Yes

The document explicitly states "The Vital Scientific APTT is an in-vitro diagnostic reagent".

No

The device description clearly states it is an "in-vitro diagnostic reagent" and describes its use in a manual method for APTT testing, involving the addition of a suspension of rabbit brain cephalin. This indicates a physical reagent, not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The very first section explicitly states "The Vital Scientific APTT is an in-vitro diagnostic reagent intended for use in a manual method in a clinical laboratory for the performance of Activated Partial Thromboplastin Time (APTT) testing..." This directly identifies it as an in-vitro diagnostic reagent.
  • Device Description: The description details how the reagent is used to determine APTT and coagulation factor assays, which are tests performed on biological samples (blood) outside of the body.
  • Intended User/Care Setting: It specifies use in a "clinical laboratory," which is a typical setting for IVD testing.

The information provided clearly aligns with the definition of an In Vitro Diagnostic device, which is a medical device used to perform tests on samples such as blood, urine, or tissues to detect diseases or other conditions.

Summary of Performance Studies

Correlation studies were performed. One study used 107 patient plasmas (30 normal, 77 undergoing heparin therapy) and was performed on the MLA 900C coagulometer. The correlation coefficient was 0.938. Another correlation study used 107 patient plasmas (30 normal, 77 undergoing heparin therapy) and was performed on an ACL-100 coagulometer. The correlation coefficient was 0.930. Day to Day and Within-run Precision studies were performed. All within-run %CV values were less than 5 %. All day to day %CV values were less than 5%.

Key Metrics

Correlation coefficient for MLA 900C coagulometer study: 0.938; slope: 0.727; intercept: 6.96.
Correlation coefficient for ACL-100 coagulometer study: 0.930; slope: 0.952; intercept: 3.76.
Within-run Precision: All %CV values less than 5%.
Day to Day Precision: All %CV values less than 5%.

Device Name:

Vital Scientific APTT (In-vitro diagnostic reagent). The Vital Scientific APTT is also tradenamed the QuikCoag APTT, and APTT. References in this document submission may use these names interchangeably.

Common Name:

Activated Partial Thromboplastin Time (APTT)

Classification Name:

Activated Partial Thromboplastin - has been classified as Class II device, as per 21 CFR 864.7925 (Product Code GFO). This device is intended for clinical use in conjunction with an analyzer to measure clot formation.

Description of the APTT

The APTT reagent is intended for use in determining activated partial thromboplastin time (APTT) and coagulation factor assays that are based on a

modified APTT. The capacity of blood to form a fibrin clot by way of the intrinsic homeostatic pathway requires coagulation factors XII, XI, IX, VIII, platelet lipids and calcium. The assay is performed by the addition of a suspension of rabbit brain cephalin with a surface activator.

Intended Use

The Vital Scientific APTT is an in-vitro diagnostic reagent intended for use in a manual method in a clinical laboratory for the performance of Activated Partial Thromboplastin Time (APTT) testing for the detection of coagulation abnormalities in the intrinsic pathway.

Labeling:

This device is labeled in accordance with 21 CFR 801.

Substantial Equivalence:

The safety and effectiveness of APTT has been demonstrated by showing its substantial equivalence to APTT-LS manufactured by Fisher Diagnostics (formerly Pacific Hemostasis) K891337.

A correlation study was performed using a total of 107 patient plasmas; 30 from patients with normal APTT values and 77 with patients undergoing heparin therapy. The assays were performed on the MLA 900C coagulometer (K884863). The correlation coefficient for all plasmas was 0.938 and the slope is 0.727 and the intercept is 6.96, indicating acceptable correlation between the two reagents. The results are plotted on the following graph.

Image /page/1/Figure/10 description: This image is a scatter plot titled "APTT reagent Correlation on MLA Electra 800C". The x-axis is labeled "Vital APTT clotting time (sec.)" and ranges from 20.0 to 80.0. The y-axis is labeled "Reference APTT-LS clotting time (sec.)" and ranges from 20.0 to 90.0. The data points show a positive correlation between the two APTT clotting times, and a trend line is drawn through the data.

A correlation study of these reagents was also performed on an ACL-100 coagulometer (K881367) in the clinical laboratory of a community hospital using

a total of 107 patient plasmas; 30 from patients with normal APTT values and 77 with patients undergoing heparin therapy. The correlation coefficient for all plasmas was 0.930, the slope was 0.952 and the intercept was 3.76, indicating acceptable correlation between the two reagents. The results are plotted on the following graph.

Image /page/2/Figure/3 description: The figure is a scatter plot titled "APTT Correlation on ACL 100". The x-axis is labeled "BioMadica APTT" and ranges from 20 to 140. The y-axis is labeled "Pacific Hemostasis APTT-LS" and ranges from 20 to 120. There is a positive correlation between the two variables.

Day to Day and Within-run Precision studies were performed. All within-run %CV values were less than 5 %. The day to day precision is the %CV of the average APTT value obtained over five days. All day to day %CV values were less than 5%. The day to day and within run precision of Vital APTT and the predicate device APTT reagent were equivalent. The results for the within-run precision are shown in Table 1 and for the day to day precision is shown in Table 2 below:
