K020801, QuickVue One-Step hCG Combo test

AI/ML (Artificial Intelligence / Machine Learning)

No
The device is a rapid visual immunoassay, which relies on chemical reactions and visual interpretation, not AI/ML algorithms. The summary explicitly states "Not Found" for mentions of AI, DNN, or ML, and the performance studies describe traditional analytical and comparison methods.

Therapeutic

No.
The device is used for the detection of pregnancy (diagnosis), not for treating a condition or disease.

Diagnostic

Yes

The device detects human chorionic gonadotropin in human urine or serum specimens to aid in the early detection of pregnancy, which is a diagnostic purpose.

SaMD (Software as a Medical Device)

No

The device description clearly states it is a rapid visual immunoassay using test devices in strip and cassette formats, which are physical hardware components.

IVD (In Vitro Diagnostic)

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

Here's why:

Intended Use: The intended use explicitly states it's for the "qualitative, presumptive detection of human chorionic gonadotropin in human urine or serum specimens." This involves testing biological samples (urine and serum) in vitro (outside the body) to provide information about a physiological state (pregnancy).
Device Description: It describes the device as measuring the presence of a hormone (HCG) in human urine or serum.
Care Setting: While it's intended for prescription use in clinical laboratories and not point-of-care, this still falls under the umbrella of in vitro testing performed in a clinical setting.

The definition of an IVD is a medical device that is used to perform tests on samples such as blood, urine, or tissue to detect diseases or other conditions. The Fastep S10 hCG Serum/Urine Combo Test fits this definition perfectly.

Device Description

Fastep S10 hCG Serum/Urine Combo Test measures the presence of the hormone Human Chorionic Gonadotrophin (HCG) in human urine or serum for the early detection of pregnancy. During pregnancy, HCG is produced by the placenta shortly after the embryo attaches to the uterine lining. The test devices are in two different formats: Strip, Cassette.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Analytical Performance:
- Precision/Reproducibility/Cut-Off Value: Negative serum specimens were spiked with varying hCG concentrations (0, 2, 4, 6, 8, 9, 10, 12, 14, 16, 18, 20, 50, 100, 150 mIU/mL). Tested in 10 replicates using 3 different lots for each format (serum strip, serum cassette). Tests were performed by three different operators for each lot in 2 runs per day for 5 days.
  - Serum Strip format: Overall Agreement values ranged from 71% to 100%. At 10 mIU/mL, agreement was 97%.
  - Serum Cassette format: Overall Agreement values ranged from 74% to 100%. At 10 mIU/mL, agreement was 96%.
  - Negative urine specimens were spiked with hCG concentrations (0, 5, 10, 12, 14, 16, 18, 20, 22, 25, 30, 35, 50, 75, 100, 250 mIU/mL). Tested in 10 replicates using 3 different lots for each format (urine strip, urine cassette). Tests were performed by three different operators for each lot in 2 runs per day for 5 days.
  - Urine Strip format: Overall Agreement values ranged from 66% to 100%. At 20 mIU/mL, agreement was 96%.
  - Urine Cassette format: Overall Agreement values ranged from 57% to 100%. At 20 mIU/mL, agreement was 98%.
  - Cut-off values established: 10 mIU/mL for serum and 20 mIU/mL for urine.
- Stability: Stable at 4-30°C for 24 months based on accelerated stability study at 50°C and real-time stability determination at 4°C and 30°C.
- Specificity / Cross Reactivity:
  - High Dose Effect: Negative urine (serum) samples spiked with high hCG concentrations (62500 to 2000000 mIU/mL). Tested by 3 different lots and 3 different operators. No hook effect observed.
  - Effects of hCG B-core fragment: Serum samples (0 and 10 mIU/mL hCG) and urine samples (0 and 20 mIU/mL hCG) spiked with varying concentrations of B-core fragment hCG (0 to 500000 pmol/L). Tested by 3 different lots and 3 different operators. Interference was observed at concentrations of 500 pmol/L and above for hCG free serum samples; no interference for serum samples spiked with 10mIU/mL hCG. Similar results for urine samples.
  - Effects of glycoprotein LH, FSH and TSH: Negative and positive samples (0 and 20 mIU/mL hCG for urine, and 0 and 10 mIU/mL hCG for serum) spiked with various concentrations of LH (300mIU/mL), FSH (1000mIU/mL), and TSH (1000µIU/mL). Samples tested using three different lots by three operators. No specific numerical results provided, but the table indicates negative samples remained negative and positive samples remained positive after spiking.
- Interference: Various exogenous compounds (e.g., Acetaminophen, Acetoacetic Acid, Ascorbic Acid, Caffeine, Ephedrine, Salicylic Acid, EDTA, Ethanol, Methanol, Albumin, Glucose, Bilirubin, Hemoglobin) at specified concentrations were spiked into hCG-free and hCG-positive samples (10mIU/mL for serum, 20mIU/mL for urine). Each spiked urine sample mixed for 5 minutes, then tested using 3 different lots. All data show no interference for the listed compounds at the stated concentrations.

9. Test Principle

It is a lateral flow chromatographic immunoassay. When the absorbent end is immersed into a sample, the sample is absorbed into the device by capillary action and mixes with the antibody-dye conjugate (mouse anti-beta HCG monoclonal antibody), flowing across the pre-coated (Goat anti HCG polyclonal antibody) membrane. At analyte concentration above the target cut off, it produces a colored test line that indicates a positive result. When analyte concentration is below the cutoff, no colored band shows in the test region, indicating a , negative result. No line in the "C" region indicates that the test is invalid.

Data show that there is no interference from pH and specific gravity of tested urine samples.

1. Comparison Studies
  A method comparison study was performed, comparing the results obtained from the Fastep S10 hCG Serum/Urine Combo Test to the results from predicate devices (QVUE). 100 each urine or serum samples were collected from 100 women (about half of them were pregnant, early stage at less than 5 weeks). Samples were randomly collected at various times throughout the day. Ages ranged from 20 to 49 years. The samples were

blind labeled. Samples were tested by three different health professionals with the proposed and the predicate devices. Each person could only perform tests for one device format. For example, a person who tested the strips could not test the cassettes. Each person tested three different lots of the device and one predicate device at the same time, but not sequentially. Typical results are shown in the following tables.

Dear Mr. Xia:

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. Iisting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
