Pregnancy Test Strip Assurance

1. **Test Strip Components:**

• **Nitrocellulose Membrane:** Acts as the medium for the migration of the sample.
• **Absorbent Pad:** Absorbs the urine sample and facilitates its movement along the strip.
• **Control Line Antibody:** Coated with antibodies that react with the control line indicator.
• **Test Line Antibody:** Coated with antibodies specific to human chorionic gonadotropin (hCG).
• **Gold Nanoparticles or Colloidal Gold:** Used as a visual marker for the test line and control line.

2. **Buffer Solution:**

• **Phosphate Buffered Saline (PBS):** Maintains pH and provides the necessary ionic strength for the test.
• **Detergents (e.g., Tween-20):** To reduce non-specific binding and improve the clarity of the test results.

3. **Stabilizers:**

• **Proteins (e.g., BSA - Bovine Serum Albumin):** To stabilize the antibodies on the strip.
• **Preservatives (e.g., Sodium Azide):** To prevent microbial growth and maintain the integrity of the test components.

### Indications for Use

The Agary Pregnancy Test Strip is indicated for:

1. **Early Detection of Pregnancy:**

• To qualitatively detect the presence of human chorionic gonadotropin (hCG) in urine, which is an indicator of pregnancy.

2. **Home Use:**

• Designed for self-testing by individuals in the privacy of their homes to confirm pregnancy.

3. **Clinical Use:**

• Can be used in healthcare settings for preliminary screening of pregnancy in patients.

4. **Monitoring hCG Levels:**

• Useful for monitoring hCG levels in women undergoing fertility treatments or those with conditions affecting hCG production.

### Instructions for Use

1. **Sample Collection:**

• Collect a urine sample in a clean, dry container.

2. **Testing Procedure:**

• Remove the test strip from the sealed pouch.
• Dip the strip into the urine sample for the time specified in the instructions (usually a few seconds).
• Lay the strip flat on a clean, dry surface.

3. **Reading Results:**

• Wait for the specified time (usually 3-5 minutes) to read the results.
• A single line indicates a negative result, while two lines indicate a positive result.

4. **Interpretation of Results:**

• Positive Result: Two distinct lines (one in the control area and one in the test area).
• Negative Result: One line in the control area only.
• Invalid Result: No lines or a line only in the test area.

### Storage and Stability

• Store the test strips in a cool, dry place away from direct sunlight.
• Do not freeze the test strips.
• Check the expiration date before use.

### Caution

• For in vitro diagnostic use only.
• Follow the instructions carefully for accurate results.
• Consult a healthcare professional for further evaluation if pregnancy is suspected or if results are unclear.
