Pemeriksaan darah yang paling sering dilakukan adalah hitung jenis sel darah lengkap (CBC, complete blood cell count), yang merupakan penilaian dasar dari komponen sel darah.
Sebuah mesin otomatis melakukan pemeriksaan ini dalam waktu kurang dari 1 menit terhadap setetes darah.


[[Berkas:Complete_blood_count_and_differential.jpg|jmpl|Hasil hitung darah lengkap dan perbedaannya.]]
Selain untuk menentukan jumlah sel darah dan trombosit, persentase dari setiap jenis sel darah putih dan kandungan hemoglobin; hitung jenis sel darah biasanya menilai ukuran dan bentuk dari sel darah merah.
'''Hitung darah lengkap''' adalah serangkaian tes [[laboratorium medis]] yang memberikan informasi tentang sel-sel dalam darah seseorang. Hitung darah lengkap menunjukkan jumlah [[sel darah putih]], [[sel darah merah]] dan [[trombosit]], konsentrasi [[hemoglobin]], dan [[hematokrit]] (persentase volume sel darah merah). Termasuk di dalamnya tes darah merah, yang menunjukkan ukuran rata-rata dan kandungan hemoglobin sel darah merah, juga dilaporkan, dan tes darah putih, yang menghitung jumlah dan jenis sel darah putih.
Sel darah merah yang abnormal bisa pecah atau berbentuk seperti tetesan air mata, bulan sabit atau jarum.

Dengan mengetahui bentuk atau ukuran yang abnormal dari sel darah merah, bisa membantu mendiagnosis suatu penyakit.
Sebagai contoh sel berbentuk bulan sabit adalah khas untuk penyakit sel sabit, sel darah merah yang kecil dapat merupakan pertanda dari stadium awal kekurangan zat besi dan sel darah merah berbentuk oval besar menunjukkan kekurangan asam folat atau vitamin B12 (anemia pernisiosa).

Hitung retikulosit adalah jumlah sel darah merah muda (retikulosit) dalam volume darah tertentu.

Dalam keadaan normal, retikulosit mencapai jumlah sekitar 1% dari jumlah total sel darah merah.

Jika tubuh memerlukan lebih banyak darah merah (seperti yang terjadi pada anemia), secara normal sumsum tulang akan memberikan jawaban dengan membentuk lebih banyak retikulosit.
Karena itu penghitungan retikulosit merupakan penilaian terhadap fungsi sumsum tulang.


[[Kategori:Hematologi]]
Pemeriksaan yang menentukan kerapuhan dan karakteristik selaput sel darah merah, membantu dalam menilai penyebab anemia.
[[Kategori:Patologi kimia]]

[[Kategori:Diagnosis medis]]
Sel darah putih dapat dihitung sebagai suatu kelompok (hitung sel darah putih).
Jika diperlukan keterangan yang lebih terperinci, bisa dilakukan penghitungan jenis-jenis tertentu dari sel darah putih (differential white blood cell count).

Trombosit juga dapat dihitung secara terpisah.

Platelet juga dapat dihitung secara terpisah.

Salah satu pemeriksaan yang paling sering dilakukan pada plasma adalah analisis elektrolit.
Dilakukan pengukuran terhadap natrium, klorida, kalium dan bikarbonat, juga kalsium, magnesium dan fosfat.

Pemeriksaan lainnya mengukur jumlah protein (biasanya albumin), gula (glukosa) dan bahan limbah racun yang secara normal disaring oleh ginjal (kretinin dan urea-nitrogen darah).

Sebagian besar pemeriksaan darah lainya membantu memantau fungsi organ lainnya.
Karena darah membawa sekian banyak bahan yang penting untuk fungsi tubuh, pemeriksaan darah bisa digunakan untuk mengetahui apa yang terjadi di dalam tubuh.
Selain itu, pemeriksaan darah relatif mudah dilakukan.
Misalnya fungsi tiroid bisa dinilai secara lebih mudah dengan mengukur kadar hormon tiroid dalam darah dibandingkan dengan secara langsung mengambil contoh tiroid.
Demikian juga halnya dengan pengukuran enzim-enzim hati dan protein dalam darah lebih mudah dilakukan dibandingkan dengan mengambil contoh hati.

Hasil hitung darah lengkap dan perbedaannya.

Hitung darah lengkap adalah serangkaian tes laboratorium medis yang memberikan informasi tentang sel-sel dalam darah seseorang. Hitung darah lengkap menunjukkan jumlah sel darah putih, sel darah merah dan trombosit, konsentrasi hemoglobin, dan hematokrit (persentase volume sel darah merah). Termasuk di dalamnya tes darah merah, yang menunjukkan ukuran rata-rata dan kandungan hemoglobin sel darah merah, juga dilaporkan, dan tes darah putih, yang menghitung jumlah dan jenis sel darah putih.
