No
The device description and performance studies indicate a standard chromatographic immunoassay with a digital reader, not AI/ML.
No.
This device is an in-vitro diagnostic (IVD) test intended to detect pregnancy, not to treat or cure a medical condition.
Yes
The device qualitatively detects human chorionic gonadotropin (hCG) in urine to aid in the early detection of pregnancy, which falls under the definition of a diagnostic purpose.
No
The device description clearly states it is a "test system" with a "chromatographic strip contained within a plastic housing" and a "digital component integral with the chromatographic strip". This indicates the device includes physical hardware components beyond just software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "qualitative detection of human chorionic gonadotropin (hCG) in urine." This is a biological sample being tested in vitro (outside the body) to diagnose a condition (pregnancy).
- Device Description: The description details a "chromatographic immunoassay" and "immunochemical reactions via component reagents that are deposited onto a chromatographic strip." These are all characteristic components and processes of an in vitro diagnostic test.
- Function: The device analyzes a biological sample (urine) to detect a specific analyte (hCG) and provides a result based on that analysis, which is the core function of an IVD.

Intended Use / Indications for Use
The FIRST RESPONSE™ Gold™ Digital Pregnancy Test is a single-use in vitro diagnostic test device intended for the early detection of pregnancy by the lay user. The test detects human chorionic gonadotropin (hCG) hormone in urine. The device is indicated for use as early as five (5) days before the day of expected period, i.e., as early as six (6) days before the day of the missed period.
The FIRST RESPONSE " Gold Digital Pregnancy Test is an over-the-counter chromatographic immunoassay for the qualitative detection of human chorionic gonadotropin (hCG) in urine. The device is intended for use as an aid in early detection of pregnancy, in some cases as early as five (5) days before the expected period, i.e., as early as six (6) days before the day of the missed period.
Important note regarding negative results: Some pregnant women will not be able to detect hCG in their urine 5 days before the expected period. If you test negative before your missed period, but think you may still be pregnant, you should re-test again a few days after your missed period.
All results should be confirmed by your healthcare provider, especially when making decisions about future medical care.

Device Description
The FIRST RESPONSE™ Gold™ Digital Pregnancy Test is a test system for the detection of human chorionic gonadotropin (hCG) hormone. Specifically, it is a screening device intended for the early detection of pregnancy by the lay user through the qualitative detection of hCG in urine as early as six (6) days before the day of the missed period. The detection of hCG in the urine of a pregnant woman is accomplished by a series of immunochemical reactions via component reagents that are deposited onto a chromatographic strip contained within a plastic housing. A digital component integral with the chromatographic strip reads and displays the result of the immunochemical reaction on an LCD (Liquid Crystal Display) screen of the device in place of the colored lines of the predicate device. Following the instructions for use provided with the device, the test is performed by placing the absorbent collection tip of the device into the urine stream for 5 seconds (or alternatively by fully immersing the collection tip for 5 seconds in a urine sample that was collected in a cup). A clock symbol will begin to blink in about 30 seconds after the urine is applied to indicate to the consumer that the test is working. The test result is read on the LCD screen of the device within 3 minutes. A "YES+" test result indicates that the pregnancy hormone (hCG) was detected (pregnant) and a "NO-" test result indicates that no hCG was detected (not pregnant).
The 510(k)-subject FIRST RESPONSE™ Gold™ Digital Pregnancy Test device and its analog predictate counterpart utilize identical immunochemical principles for the determination of hCG. They differ in that the reagent system of the 510(k)-subject device has been enhanced to include an additional monoclonal antibody capable of detecting hCG beta core fragment (hCG ßcf. hCG ßcf is produced in early pregnancy (1) and its detection is intended to improve the clinical performance of the device. Detection of hCG for also prevents or reduces the potential for a false negative test result because hCG ßcf is the major form of immunoreactive urinary hCG commonly found in later pregnancy (2, 3). In addition, the subject 510(k) device differs from the predicate device in that it provides a digital display of test result for the consumer to read in place of the colored lines of the predicate device. The digital version of the predicate device incorporates into the device housing electronic and optical components along with a microprocessor and an optimized algorithm capale of determining and correctly interpreting the assay result and displaying a simple "YES+" or "NO-" on the LCD screen. The digital device which is battery powered will display the result for at least thirty minutes after completion of the reaction. All components are integrated and unitized into the device housing.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A number of laboratory and consumer use studies were undertaken to demonstrate that the 510K-subject device is substantially equivalent to the predicate device for the detection of pregnancy as early as 6 days before the day of missed period. These studies are as follows:
- A laboratory study to demonstrate the accuracy of the 510(k)-subject device compared to the accuracy of the predicate device using urine samples quantified for hCG levels from pregnant and non-pregnant women. The study showed no discrepancies in accuracy.
- A laboratory study to determine the analytical sensitivity and cut-off of the 510(k)-. subject device using hCG standards of known concentration. The data demonstrate that the analytical sensitivity is 10 mIU/mL with a 50/50 cutoff of 6 mIU/mL for both midstream and dip method.
- A consumer study to demonstrate the ability of lay users to obtain similar results around the established sensitivity and cutoff as laboratory professionals. The data demonstrate no difference in device performance between lay users and laboratory professionals.
- A laboratory study to assess intra and inter lot precision of the 510(k)-subject device using hCG standards of known concentration. The data demonstrate no intra nor inter lot-to-lot variability.
- Laboratory studies to demonstrate that potential interfering substances and homologous hormones do not affect the performance of the 510(k)-subject device. The data demonstrate no effect on the performance of the device.
- A laboratory study to demonstrate that no high dose hook effect is observed when the 510(k)-subject is challenged with very high levels of intact hCG. The data demonstrate no effect on the performance of the device.
- A laboratory study to confirm high levels of hCG Bcf. The results of this study show no detrimental effect on the performance of the device.
- An early pregnancy detection study using urine samples from conceptive cycles to demonstrate that the 510(k)-subject device can detect hCG days before the missed period. The data demonstrate that the device can detect hCG 6 days before the missed period.
- A laboratory study to determine the performance of the 510(k)-subject device with urine samples quantified for hCG from pre-, peri-, and post-menopausal women. The data demonstrate that the potential for false positive results in the subpopulations is zero.
- A consumer self-use study to determine the ability of the consumers to perform the test and interpret the results correctly. The data demonstrate that consumers can perform the test and interpret the result correctly.
