When to Test

Detects human chorionic gonadotropin (hCG) in urine. Can be used from approximately 1 week after your expected period date. If your cycle is irregular, estimate your expected period date based on your previous cycle and test about 1 week after that date. Can be used at any time of day.

How to Use

  1. 1Open the individual foil pouch just before use. Remove the test stick and attach the cap to the opposite end of the stick.
  2. 2Hold the stick with the tip pointing down. Urinate directly on the tip for about 2 seconds (no more than 5 seconds). Note: applying too much urine may affect the result. OR collect urine in a dry, clean cup and submerge the entire reaction area for at least 2 seconds (no more than 5 seconds). Do not get the cap end wet. Do not use highly turbid urine or urine containing foreign matter.
  3. 3Replace the cap and lay the stick flat on a surface. Wait about 1 minute. First check that a line has appeared in the Control line (C) before reading the result. Avoid reading the result after 10 minutes have passed.

Reading Your Result

First confirm a line has appeared in the Control line (C) — this confirms the test has run correctly. Even a very faint line counts. If no line appears in the Control line, the test is invalid — use a new test stick.

✅ Positive
A line appears in both the Test line (T) and the Control line (C). Even a faint line on the T line indicates a positive result. Please consult a doctor as soon as possible.
❌ Negative
Only the Control line (C) appears. If your period does not start, re-test or consult a doctor.
⚠️ Invalid
No line appears in the Control line (C). The test did not run correctly. Test again with a new test stick.

Tips

Results in about 1 minute

⚠️If you are receiving hCG-containing gonadotropin medications as part of infertility treatment, they may affect the result.

Illustration created by LifeAbroad for educational purposes · Based on the official package insert (mizuho-m.co.jp)

When to Test

Detects human chorionic gonadotropin (hCG) in urine. Can be used from approximately 1 week after your expected period date. If your cycle is irregular, estimate your expected period date based on your previous cycle and test about 1 week after that date. Can be used at any time of day.

How to Use

  1. 1Open the foil pouch just before use. Remove the test stick and take off the protective cap from the tip. Attach the cap to the opposite end of the stick and hold the thumb grip. Do not push the cap in too hard — if inserted too far, it may become difficult to remove.
  2. 2Hold the stick with the absorbent tip pointing down. Urinate directly onto the entire absorbent tip for 5 seconds or longer. Urinate from the front of the tip — do not urinate on the result windows or sides. OR collect urine in a dry, clean cup and submerge the entire absorbent tip for exactly 10 seconds. Do not submerge any part beyond the absorbent tip. Do not tilt the absorbent tip upward after applying urine. Do not apply urine a second time. Do not use urine that has been left standing for a long time, or urine that is highly turbid or contains foreign matter.
  3. 3Replace the cap over the wet absorbent tip, keeping the tip pointing down. Place the test stick flat on a surface and wait 1–3 minutes.

Reading Your Result

First check that a reddish-purple line has appeared in the Control Line (○) — this confirms the test has run correctly. Then observe whether a line appears in the Test Line (□). The line may be faint or dark — any line counts. Do not read the result after 10 minutes have passed.

✅ Positive (Pregnant)
A reddish-purple line appears in the Test Line (□) — even faintly. Please consult a doctor as soon as possible.
❌ Negative (Not Pregnant)
No line in the Test Line (□). If your period does not start, re-test approximately 1 week later or consult a doctor.
⚠️ Invalid

When to Test

Detects human chorionic gonadotropin (hCG) in urine. Can be used as early as 1 week after your missed period. Can be used at any time of day.

How to Use

  1. 1Open the foil pouch just before use. Attach the cap to the back of the stick. Hold the stick with the absorbent tip facing down and urinate thoroughly onto the entire absorbent tip for about 2 seconds. OR collect urine in a clean cup and dip the entire absorbent tip for 2 seconds. Do not let the plastic body get wet with urine. Do not exceed 10 seconds in either method.
  2. 2Keep the absorbent tip facing down and cap the stick. Place it flat on a surface so the Judgement area (判定窓) is visible. Wait 1 minute. Do not hold it in your hand while waiting.
  3. 3First confirm a red line has appeared in the 終了 (Completion) area — this is the control line, confirming the test has run correctly. Then read the result in the 判定 (Judgement) area within 10 minutes.

Reading Your Result

✅ Positive
A red line appears in the 判定 (Judgement) area — even faintly — means you are probably pregnant. Please consult a doctor as soon as possible.
❌ Negative
No red line in the 判定 (Judgement) area means pregnancy was not detected in this test. If your period does not start afterward, please re-test or consult a doctor.

Reading Your Result

First confirm a reddish-purple line has appeared in the oval 終了 (Completion Window) — this is the control line, confirming the test has run correctly.

✅ Positive
A reddish-purple line appears in the square 判定 (Result Window) — even faintly — means you are probably pregnant. Please consult a doctor as soon as possible.

No line in the square 判定 (Result Window) means pregnancy was not detected in this test. If your period does not start, re-test about one week later or consult a doctor.
