Gestational anaemia, which has specific haemoglobin (Hb) reference values in each trimester of gestation, increases the risk of maternal mortality and complications both in pregnancy and in the first months of the newborn's life. The objective of this study is to evaluate haemoglobin levels in pregnant women in our population, to determine the prevalence of gestational anaemia and to propose reference values specific to them. ⋯ The prevalence of gestational anaemia in our population is somewhat higher than in countries like ours. Therefore, there is room for improvement in our current clinical protocols. It is important to assess updating analytical controls with other more adequate parameters to determine iron reserves, as this is the main cause of anaemia.

D-dimer levels are elevated in COVID 19 and they correlate to the levels of other inflammatory markers such us ferritin, fibrinogen and C-reactive protein. It may be possible to correct D-dimer value in function of inflammatory markers, thus identifying patients at higher risk of venous thromboembolism (VTE). Our objectives are estimating a corrected value of plasma D-dimer as a linear function of ferritin, C-reactive protein and fibrinogen and stablishing a cut-off point of high probability of VTE. ⋯ It is possible to estimate a D-dimer corrected value in function of ferritin, C-reactive protein and fibrinogen. Using the observed and estimated value we can obtain a residual value that performs well as a screening method to detect patients who would benefit for further VTE diagnostic testing.
