Yes — Natalist has a sensitivity of 6 mIU/ml and can detect pregnancy at 9 if HCG is above this threshold. Typical HCG at 9 is 5–25 mIU/ml. A faint line at 9 on Natalist is a meaningful result.
A faint line on a Natalist test at 9 DPO is possible but not yet reliable. HCG at 9 DPO typically ranges from 5–25 mIU/ml — Natalist has a sensitivity of 6 mIU/ml so detection is possible if you are on the higher end of the range.
If you are seeing a faint line at 9 DPO on Natalist, check whether it has colour. A true positive on Natalist should have pink colour even if very faint. Retest in 48 hours and the line should be noticeably darker if it is a real positive.
Natalist uses pink dye. A true positive line on Natalist at 9 DPO will be pink in colour — even if very faint. The key things to look for are:
A true positive Natalist line is pink and appears within the reading window. Due to the high sensitivity, very faint lines are possible from as early as 8-9 DPO. Even a very faint pink line within the reading window should be considered a positive.
Natalist has a relatively low risk of evaporation lines compared to other brands. However an evap is still possible if the test is read after the 10 minute window. Always read within the stated time.
Natalist tests are among the most sensitive available with a 6 mIU/ml sensitivity comparable to FRER. They are generally considered reliable with fewer evap and indent line issues than other strip brands.
Natalist has a low risk of indent lines.
An indent line is a colourless depression in the test strip where the test line would appear if positive. It is caused by the manufacturing process and is not a positive result. Key characteristics of an indent line on Natalist:
- Has no pink colour — appears grey or colourless - Is visible on the dry test strip even before dipping - May become more visible on inverted or enhanced photos - Does not indicate pregnancy
At 9 DPO, typical HCG levels range from 5 to 25 mIU/ml. This is a wide range because HCG levels vary significantly between women and between pregnancies.
Natalist has a detection threshold of 6 mIU/ml. This means:
The Mayo Clinic notes that HCG roughly doubles every 48 hours in early pregnancy. If you retest in 48 hours the line should be noticeably darker if HCG is rising as expected.
9 DPO is the very beginning of the realistic detection window for the most sensitive tests. A negative at 9 DPO is still common and does not rule out pregnancy. If you see a squinter at 9 DPO on a sensitive test it is worth taking seriously.
48 hours is the recommended retest window after a faint result at 9 DPO. This is because HCG roughly doubles every 48 hours in early pregnancy — retesting after this interval gives the best chance of seeing a meaningful change in line darkness.
FMU is essential at 9 DPO. The difference between FMU and afternoon urine can be the difference between a faint positive and a negative at this stage.

It is possible but not yet reliable. Check that the line has pink colour and appeared within the reading window. Retest in 48 hours.
Yes. Natalist has a sensitivity of 6 mIU/ml. Typical HCG at 9 DPO ranges from 5–25 mIU/ml, so detection is possible in most pregnancies.
Evap lines on Natalist typically appear after the reading window, have no pink colour, and appear grey or colourless. Natalist has a low risk of evaporation lines. A true positive Natalist line is pink and appears within the reading window. Due to the high sensitivity, very faint lines are possible from as early as 8-9 DPO. Even a very faint pink line within the reading window should be considered a positive.
An indent line on Natalist is colourless — it has no pink colour and appears grey. Natalist has a low risk of indent lines. It is a depression in the test strip, not a positive result.
48 hours — FMU is essential at 9 DPO. The difference between FMU and afternoon urine can be the difference between a faint positive and a negative at this stage.
Natalist has a sensitivity of 6 mIU/ml — Other sensitive brands like FRER and Clearblue have similar or lower detection thresholds.
At 9 DPO, HCG typically ranges from 5–25 mIU/ml. If you are on the lower end of this range or implanted later, your HCG may barely exceed Natalist's 6 mIU/ml threshold, producing a faint line. Retest in 48 hours — a rising HCG will produce a darker line.
