Frequently Asked Questions

The kit detects ​Pregnancy-associated Glycoproteins (PAGs)​​ in bovine serum, plasma, or whole blood. PAGs are placental biomarkers that rise significantly during early pregnancy, enabling accurate pregnancy diagnosis.

Results are ready in ​15–20 minutes​ after adding the sample and diluent. ​Do not interpret results after 30 minutes, as they may become invalid.

Compatible samples include:

  • Serum/Plasma: Collect after full coagulation. Store at 2–8°C for ≤7 days or freeze at ≤-20°C for long-term storage (avoid repeated freeze-thaw cycles).
  • Whole Blood: Collect in anticoagulant-treated tubes (e.g., EDTA, heparin). For storage, mix with erythrocyte preservation solution (e.g., Alsever’s solution) at a 1:2–4 ratio and keep at 4°C for 1–3 months.

No. Follow these simple steps:

  1. Equilibrate reagents and samples to room temperature.
  2. Add ​1 drop of serum/plasma/whole blood​ to the test cassette well.
  3. Add ​2 drops of diluent​ to the same well.
  4. Read results at 15–20 minutes.
  • Positive (Pregnant)​: Both ​Test line (T)​​ and ​Control line (C)​​ are visible.
  • Negative (Non-pregnant)​: Only the ​Control line (C)​​ appears.
  • Invalid: No control line (C) → Repeat the test with a new cassette.
  • Storage: Keep unopened kits at 2–30°C (35.6–86°F), protected from light, moisture, and extreme temperatures.
  • Shelf Life: 12 months from manufacture date (unopened).
  • After opening: Use test cassettes immediately to avoid moisture absorption.

Avoid using:

  • Hemolyzed, turbid, lipemic, or highly viscous samples.
  • Improperly stored whole blood (e.g., without preservation solution).
  • Repeatedly thawed serum/plasma.

No. Each cassette is for single-use only. Dispose of used cassettes according to local biohazard guidelines.

The test is breed-independent, as it targets PAGs levels. Ensure samples are collected and processed as per the manual to avoid operational errors.
