Is it from the newborn screening test group which is done routinely for all newborns on the 5 the day by filter paper?

Secondly do you have an chid in your immediate family with galactosemia?

Do not worry.

Pl write to me when it was done, What was the feeds at that time,

and whether baby has any problems?

If it was routine test , it has to be repeated .

Equivocal means that something can not be excluded and at the same time it is not 100% sure of the illness also.
In other words doubtful validity.
Lab tests are a guide to diagnosis only but it always has to be interpreted in a proper way with clinical findings,symptoms and signs.
Lab errors are also common especially with filter paper samples as only 2-3 drops of blood from baby,s heel prick is tested for many conditions!

Kindly answer my quest ions and I will get back to you.
God bless

Thanks for your quick response Dr. Uma.
Its from newborn screening test group which is done routinely for all newborns.this test was done on the 2nd of child birth by heel prick method.
we do not have any child in our immediate family with galactosemia.
Baby is doing fine as of now.. feeding well, she is active and no other problems or symptoms.

Thanks for your reply.

The plan would be as follows.
You must urgently repeat the screening test once again.
It will be nice if thy can do a blood galactose level and also test for an enzyme called galactose -1- phosphate uridyl transferase level in blood.
The can be done in a well establishd lab your city.

The screening test can be repeated in the same lab through the doctor of your maternity hospital.

Let us wait for the repeat screening test and meanwhile you enquire about the other tests.

Follow up the results with the lab to get the results asap!

I hope and pray with you that it was a false positive result.!

Good luck
God bless

We have an 11 year-old daughter who was diagnosed with galactosemia 2 days after birth. Dr, Heindenreich was her doctor, and we were never able to find out if she is classical or has the duarte gene. She is 61 lbs and cannot gain weight. We fill her up on high carb meals, snacks, etc.. Her pediatrician is worried, as she lost 1 lb over the past year, instead of gaining weight. As she heads into puberty she needs to gain weight. She is developing underarm hair and showing good signs. What would you suggest to help her gain weight?

Hi, My 3-month baby was diagnosed with cataract . She had undergone operation in both the eyes. My corporate health insurance policy covers treatment for all congenital internal diseases of my family. However, my insurers have rejected my claim by classifying her case as congenital external disease . There is conclusive evidence if the cataract was congenital or not in the first place. In fact at the time of birth, the paedatrician informed us that she was healthy. Am not sure if he missed to diagnose the cataract then or cataract developed later on due to some reason. Can someone please advice whether cataract is considered as an internal or external disease? Regards, Gaurav
