Yes — Equate has a sensitivity of 20 mIU/ml and can detect pregnancy at 20 if HCG is above this threshold. Typical HCG at 20 is 1500–5000 mIU/ml. A faint line at 20 on Equate is a meaningful result.
A faint line on a Equate test at 20 DPO is a meaningful result. HCG at 20 DPO typically ranges from 1500–5000 mIU/ml — well above the 20 mIU/ml sensitivity of Equate in most cases.
If you are seeing a faint line at 20 DPO on Equate it is very likely a true positive, particularly if the line has pink colour and appeared within the 3 minute reading window. Retest in 48 hours with FMU and the line should be noticeably darker.
Equate uses pink dye. A true positive line on Equate at 20 DPO will be pink in colour — even if very faint. The key things to look for are:
A true positive Equate line is pink and appears within the 3-minute reading window. Lines that appear after the window or without clear pink colour should be treated with caution.
Equate can occasionally produce evaporation lines. An evap line typically appears after the reading window and has no colour. If the line on your Equate test appeared within 10 minutes and has pink colour it is more likely to be a true positive.
Equate tests are a Walmart own-brand and are widely used due to their availability and low cost. Some users report indent lines and faint evap lines. Results should be read within the stated window.
Equate has a medium 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 Equate:
- 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 20 DPO, typical HCG levels range from 1500 to 5000 mIU/ml. This is a wide range because HCG levels vary significantly between women and between pregnancies.
Equate has a detection threshold of 20 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.
20 DPO is approximately 5-6 weeks pregnant. HCG levels are high and rising rapidly. Digital tests and all strip tests should give clear positive results. If testing at 20 DPO and still getting negatives with a missed period this needs medical assessment.
48 hours is the recommended retest window after a faint result at 20 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.
Any urine sample gives a reliable result by 20 DPO but FMU remains best practice.

Yes — a faint line at 20 DPO on Equate with pink colour that appeared within the reading window is likely a true positive. Retest in 48 hours to confirm progression.
Yes. Equate has a sensitivity of 20 mIU/ml. Typical HCG at 20 DPO ranges from 1500–5000 mIU/ml, so detection is possible in most pregnancies.
Evap lines on Equate typically appear after the reading window, have no pink colour, and appear grey or colourless. Equate has a medium risk of evaporation lines. A true positive Equate line is pink and appears within the 3-minute reading window. Lines that appear after the window or without clear pink colour should be treated with caution.
An indent line on Equate is colourless — it has no pink colour and appears grey. Equate has a medium risk of indent lines. It is a depression in the test strip, not a positive result.
48 hours — Any urine sample gives a reliable result by 20 DPO but FMU remains best practice.
Equate has a sensitivity of 20 mIU/ml — Other sensitive brands like FRER and Clearblue have similar or lower detection thresholds.
At 20 DPO, HCG typically ranges from 1500–5000 mIU/ml. If you are on the lower end of this range or implanted later, your HCG may barely exceed Equate's 20 mIU/ml threshold, producing a faint line. Retest in 48 hours — a rising HCG will produce a darker line.
