Hello Doctors. My Wife age is 40, and has went three miscarriage in a time frame of 3 years. We have also done some blood related test like ANA, Anticardiolipin IGH, IGM, lupus anticoagulant in first and third pregnancy but all the test were negative. Now before the 4th Pregnancy my gynecologist has referred to hematologist and hematologist asked me to go for the test by "Hereditary & acquired Hypercoagulability Workup" test Is it necessary to take this test as it costing 18000 in bangalore.
