Well, I went to the MD today and asked him to order the MN blood group test for me.  He agreed but we couldn't find it on the testing menu.  

Anyone have any more info about what to ask for?  I can use Quest or Labcorp.

Thanks!

Whoever is putting in the orders for the test needs to understand that this specific test code should be found under the tests for bloodbank in a hospital or reference lab ie. lab corp or quest.

I think I figured it out, it's another antigen, like the Lewis.

It is not on the QML lab forms here either ... but my doctors are willing to write it down by hand on the form!!!  Labs are happy to comply.   They are not on the forms because they are not popular tests, but any lab that performs general blood tests (cholesterol, vitamins, minerals or whatever blood tests, should know what we are asking ...

I had my Lewis test through Quest 12 years ago.  I have just been through all of this.  My son's doctor didn't have any idea what to order.  He uses LabCorp.  I called the local office and the national office of LabCorp.  They do not do these tests.  

My son's doctor wrote the order after the hospital blood bank told us how to write it. Then we had it drawn at the office and it was sent to the blood bank.  We still have not gotten the Lewis or A1 results.

Type and Cross (of course)
Phenotype:
Lewis A
Lewis B
MN
A1/A2

We were told by the blood bank that in actuality, they only test the A1, not the A2.  If A1 is negative, A2 is assumed.

you are mixing up the A subtypes with that of the lewis antigen testing

you do not need the A1 or A2 subtype testing, since you are a B blood type

subtypes of A are only necessary for an A blood type individual or AB

lewis a and lewis b have nothing to do with the subtypes of A

hope this is more clear

subtypes of A are only necessary in A individuals or ABs

lewis results however, are the following
Le(a-b+) always secretors
Le(a+b-) always a non-secretor
Le(a-b-) can be secretors or non-secretors, this phenotype is
         only about 5%-6% of caucasians
Le(a+b+) these people are always weak secretors, This phenotype
         is very rare and occurs almost exclusively in Asians. called Bombay

you will not get the A1 or A2 being a B

these labs do not have the necessary regents, which are very expensive, and have an expire date, so no, not all labs know what you are talking about

, yes labrat, my son is an A.  I wanted to subtype him.  We already knew he was an A+ from his times of donating blood.

Lola, his dad is an A+, not AB.  I am a B+.  All three of my children are A+.

Would this be the correct terminology to request blood tests from a doctor?

Serotype panel, including:
  • ABO blood type test
  • If blood type is 'A', A1/A2 subgroup test
  • Rhesus type (Rh+/Rh-) test
  • Lewis Blood Group test:
       >Phenotype test: Le(a+b-), Le(a-b+), Le(a-b-), Le(a+b+)
       >Secretor/non-secretor (Se gene) test
       >MM/NN/MN antigen subgroup test
