No there, is no specific blood test to check for twins, although higher than normal HCG levels in a blood test may be because of twins, although it is no where near accurate for predicting a twin pregnancy.
The process for conducting a paternity test for twins involves collecting DNA samples from the twins and the potential father. These samples are then analyzed to determine the genetic similarities and differences between the twins and the potential father, which can help establish paternity. The results of the test can provide conclusive evidence of whether the potential father is the biological father of the twins.
Assuming there's no question the babies are identical twins then, no. A paternity test on one will answer the question. However if they are fraternal twins (not identical) then, yes, each must be tested.
