Conclusion: 
There are very conflicting results for normal values of white blood cells and lymphocytes in pregnancy. In our study Lymphopenia and raised NLR do not seem to be common findings in confirmed pregnant cases of COVID-19 but can help determine morbidity as patients that had lymphopenia and raised NLR displayed severe symptoms, were more unwell and needed high dependency unit admission. The limitation of our study is its small number but we recommend lymphopenia and raised NLR as an important parameter for escalation of care.
