- Reference values are usually based on blood samples from healthy men or non-pregnant women. Blood samples from pregnant women may be compared with these reference values. Correct references for pregnancy can be extremely important for clinical decisions such as ablatio placentae, appendicitis, premature rupture of membranes and preeclampsia. Previous studies of normal variations during third-trimester pregnancy are incomplete. Blood samples during pregnancy weeks 33, 36 and 39 as well as 1-3 h postpartum were collected from pregnant women with dietary iron supplement and at least one previous pregancy without a history of hypertension or preeclampsia. When the sampled values were compared with the present reference values from men and non-pregnant women, the following differences were found during normal pregnancy: Haemoglobin and ferritin were reduced, CRP was slightly elevated, WBC (white blood cell count) and HNL (human neutrophilic lipocalin) were elevated during pregnancy and significantly increased postpartum. Albumin was reduced. ALT and AST were slightly elevated and GGT was unchanged during pregnancy. ALP, D-dimer and fibrinogen were elevated. Uric acid increased during the third trimester and thrombocyte count decreased. Separate reference values for pregnant women are essential for correct diagnostic decisions during third-trimester pregnancy. Elevated levels of D-dimer do not necessarily indicate ablatio placentae. A diagnosis of progressive preeclampsia cannot be based on increasing uric acid levels and reduced platelet count in a stable clinical condition. HNL signals activation of neutrophilic granulocytes and can thereby offer a helpful tool for diagnosing infection during pregnancy and postpartum.

- Aim: To relate cardiac biomarkers, such as cystatin C and growth differentiation factor-15 (GDF-15) in saliva to myocardial infarction (MI) and to periodontal status, and to investigate the relation between salivary and plasma cardiac biomarkers. Materials and Methods: Two hundred patients with MI admitted to coronary care units and 200 matched controls without MI were included. Dental examination and collection of blood and saliva samples was performed 6–10 weeks after the MI for patients and in close proximity thereafter for controls. Analysing methods: ARCHITECT i4000SR, Immulite 2000 XPi or ELISA. Results: The mean age was 62 ± 8 years and 84% were male. Total probing pocket depth, fibrinogen, white blood cell counts and HbA1c were higher in patients than controls. GDF-15 levels correlated with most of the included clinical variables in both study groups. No correlation was found between plasma and saliva levels of cystatin C or GDF-15. Conclusion: Salivary cystatin C and GDF-15 could not differentiate between MI patients and controls.
