How easy was it to use our calculator? Did you face any problem, tell us!

The hCG Calculator is used to find the HCG test result and to assess pregnancy.Is the pregnancy developing properly and to confirm the pregnancy? 

Let’s have a look, at how the hCG hormones density is essential in confirming the pregnancy.

What is HCG?

The hCG(Human Chorionic Gonadotropin) is a confirmation of the pregnancy after fertilization and development the placenta starts to develop and the release of hCG. 

The hCG is also referred to as the pregnancy hormone as it is present in large quantities during pregnancy. The HCG levels chart by day can be a good indication embryo has been implanted in the Uterus.

hCG doubling time:

In the first 4 weeks of a viable pregnancy, the HCG level typically doubles after every 2 to 3 days. After 6 weeks of pregnancy HCG doubles every 96 hours.

If your baseline level is higher than 5mlU/ml, your doctor may prescribe a repeat test in a couple of days as the hCG level may be doubled. You may be amused to learn the HCG doubling time calculator may provide you with all the information required. The HCG is a hormone produced at the highest level at the start of pregnancy. Its production level is an indication a woman has been pregnant.

Normal hCG doubling time chart:

hCG level Doubling Time Expected
Under 1200 mIU/ml Between 30 to 72 hours 
1200-6000  mIU/ml Between 72 to 96 hours 
Over 6000  mIU/ml Over 96 hours

Indication of the hCG:

There are various hCG level and you can spot it by the following indication:

  • Severe stomach pain or bloating from Uterus, rapid weight gain, and chest pain and it is an indication of early pregnancy. 
  • Some women may see a decrease in Urination, swelling, or sudden numbness in one side of the body. 

 The hCG calculator can spot these indications if you have symptoms of what is going on in your body.

When is it best to detect hCG?

Usually, hCG is produced during the first 8 to 10 weeks of pregnancy. The production of this hormone is so fast that you can easily get to know whether you are expecting it or not. But when you sleep during the night, you are not likely to pee again and again. 

The level of HCG hormone increases in the urine. That is why it is advised to test your pregnancy in the morning to get finer results.To find out the time, and how many weeks old a pregnancy is conceived by  hCG calculator. The conception may require 8 to 10 weeks before to spot hCG easily. 

hCG levels chart:

The HCG levels chart of women after 3 to 18 weeks in the hCG levels chart and all the values in milli-international units per milliliter (mIU/mL). The HCG doubling calculator finds all the values in sequence for women after fertilization and implantation of the embryo.

Pregnancy week Range of hCG levels in milli-international units per milliliter (mIU/mL)
3 weeks 5–72 mIU/mL
4 weeks 10–708 mIU/mL
5 weeks 217–8,245 mIU/mL
6 weeks 152–32,177 mIU/mL
7 weeks 4,059–153,767 mIU/mL
8 weeks 31,366–149,094 mIU/mL
9 weeks 59,109–135,901 mIU/mL
10 weeks 44,186–170,409 mIU/mL
12 weeks 27,107–201,165 mIU/mL
14 weeks 24,302–93,646 mIU/mL
15 weeks 12,540–69,747 mIU/mL
16 weeks 8,904–55,332 mIU/mL
17 weeks 8,240–51,793 mIU/mL
18 weeks 9,649–55,271 mIU/mL

You may be in a better position to find your  HCG doubling level by HCG calculator how many weeks pregnancy lasts. 

Terms related to hCG level:

Understand that there are some related terms they need to understand before finding any value by the HCG levels calculator.

First hCG1 Level or First β-hCG Level:

The first hCG1 level is measured during the start of the pregnancy. It is measured in mIU/ml. A unit is based on the mass and volume of the Urine, and these changes may happen in the women’s body at the beginning of pregnancy. The hCG levels chart by day can be used to find your First β-hCG Level. The HCG calculator IVF gets the initial values of the first β-hCG Level.

Second  hCG2 level or Second β-hCG Level:

The second hCG2 or Second β-hCG Level  is measured after some time of pregnancy and it is quite convenient to use the hCG doubling time. The HCG doubling time calculator makes it easy to spot the hCG2 or Second β-hCG.The beta hCG calculator is specially designed to get the  first β-hCG Level.

Time Measurements:

The time between the First β-hCG Level and the Second β-hCG Level is the time difference between the two measurements. The normal hCG doubling time chart is good to find HCG levels doubling and the difference in measurements.

The formula for the hCG doubling time can be calculated as

T2=[T/log2(hCG2/hCG2)]
One Day Increase:
The one-day increase formula does include the 24 hours time after pregnancy, the hCG calculator generates all the values in a matter of seconds.

I1=100.[(2^(24/T2)-1]

Two-Day Increase:

The two-day increase formula does include the 48  hours time after pregnancy:

I2=100.[(2^(48/T2)-1]
Example:
First hCG1 is 31 mlU/ml, and 54  mlU/ml, and the time measurement is” T” 3 days. Then what is the T2 value?

Given:

hCG1=31 mlU/ml

hCG1=54 mlU/ml

T=3 days

T2=?

Sol:

Now by the formulas the doubling time:

T2=[T/log2(hCG2/hCG2)]

T2=3.75  days 

We can find the doubling time by the HCG doubling time calculator.

Working of hCG calculator:

The HCG levels calculator requires the input data to find the dubbing time:

Input:

  • Enter the first hCG1 level
  • Enter the second hCG2 level
  • Write the time difference 
  • Hit the calculate button to find hCG value

Output:

The HCG calculator generates the following output information:

  • The difference between the first hCG1 level and second hCG2 level 
  • % difference between the first hCG1 level and second hCG2 level
  • Doubling time of hCG hormone
  • One day increases in percentage 
  • Two-day increase in percentage

FAQs:

How much should hCG increase in 48 hours?

Can hCG levels be low at 8 weeks?

When low hCG levels are detected, it’s often because a pregnancy that was thought to be between 6 and 12 weeks is actually not that far along. An ultrasound and further hCG tests can be used to calculate the gestational age correctly. This is usually the first step when low hCG levels are detected.
