When
the FetalMetrics.com Website Should Not
Be Used
Who
Should Not Use This Website
There are a number of conditions that should
be considered contraindications to the use
of ultrasonographic fetal biometric measurements
for the purpose of estimating fetal weight.
While these conditions are not common, they
indicate that there may be additional factors
that may influence fetal weight that cannot
be accounted for by using the standard ultrasonographic
fetal measurements and the associated ultrasound
fetal weight estimation equations. If you
or your fetus have (or if you think that
you or your fetus might have) any of these
conditions, YOU
SHOULD NOT USE THIS WEBSITE.
Among these conditions are the following:
Contraindications
to Use of FetalMetrics.com for Estimating
Fetal Weight
| a. |
A multiple gestation (e.g.,
twins, triplets, or a higher order pregnancy) |
| b. |
A known or suspected fetal anomaly
|
| c. |
A known or suspected congenital syndrome |
| d. |
A known or suspected chromosomal abnormality
(e.g., Down’s syndrome) |
| e. |
An Rh factor incompatibility between
the mother and her fetus |
| f. |
A major antigen incompatibility between
a mother and her fetus |
| g. |
Known or suspected hydrops fetalis |
| h. |
Oligohydramnios |
If you or your fetus have –
or are suspected to have – any of
these conditions, DO
NOT ATTEMPT TO USE THIS WEBSITE for
the ultrasonographic estimation of fetal
weight. The results will not be accurate
given your special circumstances.
IF YOU HAVE (OR ARE SUSPECTED
TO HAVE) ANY OF THE ABOVE-LISTED CONDITIONS,
DO NOT ATTEMPT TO USE THIS WEBSITE FOR THE
PURPOSE OF ESTIMATING FETAL WEIGHT
Limitations
for Use
This system is designed for use only by
women who DO NOT
HAVE any of the above-listed conditions
that are listed under items (a)-(h), as
well as a number of other rare abnormal
conditions that might affect their pregnancy.
This system WILL
NOT be able to provide you with an
accurate ultrasonographic estimate of fetal
weight if you or your fetus have (or if
you suspect that you or your fetus might
have) any of these preceding conditions,
as well as a number of other uncommon medical
conditions that can affect fetal weight.
If you or your fetus have (or if you suspect
that you or your fetus might have) any of
these above-listed conditions as well as
any others that might influence the reliability
of ultrasonographic measurements of fetal
size, please exit now and DO
NOT ATTEMPT TO USE THIS WEBSITE.
The ultrasonographic estimation of fetal
weight under these circumstances is beyond
the scope of applicability of the ultrasonographic
fetal weight estimation equations that are
used by this website, and the RESULTS
WILL NOT BE ACCURATE.
